Find the Empirical Formula Given Percents 

"if u find a white unknown powder on ur train...."

What's up players? LMAO

why can't you be my actual chem teacher. You make things seem so much simpler than my real chem teacher does

if only my teacher could teach like this. I would circle the whole class room to celebrate!

using this for my chem final tomorrow, thanks mate

"white powder that you found on the train" i'm crying

helpful tip, don't round up the molar mass(atomic) wait till you get your answer, then round up

we gonna circle it to celebrate, LOL

you've actually taught me what my pre-ap chemistry teacher couldn't! i am forever grateful to you sir!

you're supposed to assume you have 100 g of each element. This allows you to say you have 48.38% = 48.38 g C, etc. Then divide these by the MW to get the # of moles of each. The rest of the steps are the same. Assuming you have 100 g just makes it easier for people like me (an engineering student) whose anal about units.

I'm taking AP Chem this year and you're the best refresher on RU-vid! Helped me finish my summer assignments!

I found this video funny and educational

I learned more from you in the past five minutes then I have learned in the past 2 weeks about this stuff. Thanks! I won't fail my quiz tomorrow! 😂

I know this is 7 years late, but I've had bad luck trying to find a channel that actually explains concepts well and I somehow bumbled across your channel... omg thank god I found you. I think I would've failed my chem test if I didn't find you. Plus the added size doesn't matter joke at the beginning killed me.

When you take a chem. 120 course at Rider University and this person ON RU-vid teaches better than a professor for the class that cost +$2,000. Thanks man!!

Saved my life. Honestly I would pay for him to be a replacement for all chemistry textbooks

Why can't all teachers teach this way? I love you! I totally get this after hours of eating combos and crying.

oh look white powder! lets find out what its made of xD

Wow I can not believe how easy this was.

GOD BLESS YOU CHEMIST NATE I HAVE A CHEM TEST TOMORROW AND I MISSED THE LAST FEW DAYS OF THE UNIT YOU SAVED MY GPA

Wow! Our text doesn't say anything about rounding the resulting moles to determine the empirical formula! This made it attainable. Thank you!

hi. i'm from iran , in our country we are not allowed to use calculator in the exam, specially in the university entrance exam which is called konkur, in this exam we have have about 35 minutes to solve 35 chemistry questions. each question has exactly 1 minute, and they give us the most difficult questions ... i just wanted to share this with people around the world who thinks that their exams are hard.... please pray for me and wish me luck ...

I've never had a fun science teacher but this video let me vicariously live through an enjoyable Chemistry lesson

This video really helped me to understand the concept. Maraming Salamat (Thank you) for sharing this!

Thank you, im literally in my lecture hall 10 min before before my exam, I finally get it 😭

Thanks school administration for scheduling APUSH and Chem on the same day for midterms. This was very helpful.

Loool. "whatsup players?" . I died :'''D

I seriously had 3 tutors explain it to me, absolutely nada, and then I look this up and BAM! Got it! Thank you so much!!

I subscribed just because of the intro lol

I too love to celebrate upon finding the result. That circle was the cherry on top. Good day, SIR

I have my chem final tomorrow and i completely forgot how to do this until this video.... thank you for this refresher!

Methyl acetate was on the train?!?!?!

my teacher took 50 minutes to explain this... yet she still had me confused. you my friend have saved me

Thanks, used to refresh me. My final exam for chem is tomorrow! Thanks!

AMEN U HELPED ALOT EVEN AFTER 6 YEARS AFTER UPLOAD G

I want to cry. Thank you SO MUCH for being hilarious right now while I pass out from exam anxiety. Thank you!

Lmfaooo the opening 😭😂

I missed two of my chem classes and the professor hates going over things again. You just helped me by one video.

I really got to thank you because this video was the only video I could find where you're just given percentages and not some other piece of information, (i.e. g/mol) and that's exactly what I was looking for!

THANK YOU SO MUCH I’ve an exam tomorrow and I’ve lots that I didn’t understand during class. This helped me

He used simple tools for this but he make it so clear and simple .. we're so thankful ♡

Honestly might be the funniest and most helpful vid I’ve ever watched

great video! the little scenario in the beginning helped me understand why we would do this in the real world

Just finishing a lab by myself because my partner is MIA (did absolutely no work). So not in a great mood. Just made me laugh my ass off in the first few seconds so good for you.

OMG without you i dont think i would have understood this at all. Highest thanks

Thanks for this actually i forgot how to find it after doing the whole syllabus of chemistry 😅 This really helped me.

Actually this is exactly what we did in class but you did it better. You are a beautiful person. Thanks you.

dam bro i came here to cheat on my test, but i stood for you and them memes

"You know how i know? Cause i looked it up on my table." 😎

This video was awesome😭 thank you for making me smile after what seemed like forever of crying of frustration over damn chemistry

Why aren't you teaching my chemistry class???

Had to re-module my principles of inorganic chemistry subject as I got a big fat F for that module.Resorted in watching your videos as I still couldn't understand what my lecturers taught me,and finally achieved an A!Thanks for saving my GPA chemist Nate! :)

thanks so much for making this video, it has greatly increased my understanding on the topic, which I am struggling on in chemistry.

I've learned more in this video alone than I've learned in 10 months of chemistry

I'm cramming for a chem exam and let me tell you. I was expecting anything except "What's up players, does size matter?" When I clicked on this video. I don't know how to feel.

I found your enthusiasm infectious and your explanation very helpful thank you very much.

This is so helpful for someone who missed a class like me. Thank you so much!

nice when a teacher actually explains what to do IN STEPS. mine never have.

This video is ultimate, it doesn't have near as many views as it should

What about question like this? Complete combustion of 0.1595g of menthol produces 0.4490g of carbon dioxide and 0.1840g of water. Determine empirical formula of the compound? How can know what is Methanol made out off? Equation is methanol+oxygen=carbon dioxide+water. Do I bring oxygen to right hand side?

This was funny, but it also helped me greatly understand it so thank you!

idk what this intro is but i’m loving it

I used this on my Chemistry homework and followed all the steps, everything was correct and even double checked my calculations and kept getting the wrong answer. On the last part where you said if a number in on decimal to round it, if its rounded to the next number you then multiply by 2 and gives you the final whole number. Using the (x2) does not work and is incorrect. Therefore, you don't have to multiply by 2, just round to the nearest whole number.

My teacher didn't explain this but this video was really easy to understand. Thanks!

THE INTRO THO!! XD

you teach in a great way I hope you would be my teacher. you used a ............I dont know................a clever way .......to completely connect and interact with the listener

That you for the most simple explanation of empirical formulas.

This guy taught this better then my chemistry teacher

Thanks sooo much dude! I have a chem test tomorrow and I lost my paper where I wrote all of this so you definitely helped refresh my memory!!

I'll be honest, I normally use my nose instead of taking the "unknown white powder" to the lab It just saves time...

Thanks a lot mam, I was just starring on the question, and you helped me...

thank you so much! our teacher was gone the day we were supposed to do this so I had to figure it on my own I had it but I forgot how to do it now I won't forget

the best kinds of tutorials are the ones with humor

Man, my Biology teacher was like this last year and I loved his class. Now our chemistry teacher is pretty boring and the class isn't engaging at all. Probably why half of the students are browsing dank memes (including me at times)

You're an amazing teacher

This dude is literally saving my grade

I never thought I'd live to see the day when Dwight from the Office teaches me chemistry

thank you i was stuck what to do when it was 1.5 , thanks for making this video clear and quick to the point

LIFESAVER for the test! Thanks mate! Keep making these videos! you really simplify my overly complicated book!

You just put me in a better mood, thanks pal

Thank you so much it was so helpful I understand you more than my teacher...

i learned more from this video than my whole chemisty class

I like your solving method, and I like your way of explaining, Respect.

I am already guessing that u know it but let me say that 1 more time. ..u just saved my life :")

Thank you so much. This is very helpful but a bit of constructive criticism, I must say I wish you added units for the calculation. Just so I could understand the process of how they cancel out a bit better and if you could also add significant figures in next time that would be great, I have to hand it to you though. All in all thumbs up! :)

I learned more stuff in 5 and a half minutes than in two days of chem, holy sh-

YOUR A BLOODY LEGEND MATE CHEERS

I finally learned something this semester! Thanks man. Love your teaching style.

It was quite helpful to me, as well as it was quite short. Thanks so muuuuch.

the opening line absolutely sENT ME man I am shook

greatest teaching video ive every watched, thank you so much

thank you so much dude!!!...I am so rocking my finals tomorrow

I was already dead at the first 10 sec. Thank you so much for your jokes and content!

This is how all chem classes should be taught.

man man man if u see how my Prof explain this..!!!. Thank you soo much, you made it really easy for me. Thank you

great video mann. you explained it better than my teacher lol

Conveniently this also works if you're given grams from the start and not % composition!

My teacher just shows us powerpoints. :(

Can somebody please help. Im stuck on the third instruction. K=29 Cr=1 O=8 The example on the video is not the same so I dont know what to multiply.

you're actually saving my life
