Haha yeah...I think because it's better to find and discover it yourself than waiting or relying on someone to introduce it to you for you to learn...or maybe because of Trust... losing trust or having no trust at all can affect the learning progress...hmmm?...just my own opinion...hahaha good day...
First year university and you are saving me already! Watched your vids since high school but now you're helping even more after I fell behind first week due to hearing issues! Thanks!
sir i have a confusion there. how could we determine the percent abundance of element having 3 or more isotops by using your formula.what would we write on the place of p3.
@Alex think about it if p1=x p2=1-x that means if p1=40 then p2=60 and if you set p3 as 1-(1-x) then p3 would be 100-60 which means p3=40 and if you add everything up youll have total of 140%
dear TheOrganicChemistryTutor, you quite literally are a hero to me. you just explained an hour worth of yip yap chemistry from my teacher when he taught this topic today, in 10mins and i actually understood everything. thank you sir.
My chemistry sir gave me an exact same question like this and for hours i was struggling to solve that ....... and then came across with this video...❤ I have no words to express my gratitude to u ..... Thank you soo much ......❤
Your videos are the only ones I come to when I am struggling with something. Thank you, I am ALWAYS able to understand my lesson because of you. I'm a freshman in college now, majoring in forensic science, and I've watched your stuff since middle school!
THANK YOU thank you!! Honestly this was a great help and the process was paced just slow (but not too much) enough for my brain to handle. I think it's finally starting to connect! This is one of my favorite videos now.
hi! quick question. so do we always use the x-1 when we calculate percent abundance or will that change depending on the values we get in the question?
The total abudance is 1=x+y. To get the Y youll use 1-x. The total is always one. We can use 1-x if it was two variables only unless the question is the abundance of 3 isotopes which you can add z
i literally did this when i was trying to solve it the first time but then i thought i was complicating myself so i decided stop and try later,it really was that easy ,wow
U can’t this method only works for two if u wish to find the percent abundance for 3 u would have to be given one of the percent abundance’s in order to do so if u do happen to get another percent abundance then ur gonna do 1-(P1+P2+x) then multiply that to the third mass of ur isotope
Professor Organic Chemistry Tutor, thank you for showing How to Find the Percentage Abundance of Each Isotope in AP/General Chemistry. Problem solving is the best way to learn Chemistry and all related courses in Science and Engineering. This is an error free video/lecture on RU-vid TV with the Organic Chemistry Tutor.
when given the atomic mass of each isotope, and you're trying to find the abundance, how do you know which mass will have the variable (1-x) and which mass will have the variable (x)?
Hey, anyone know what to do with this stuff. When A is mass number, Z is atomic number, and element is Neon: A was 20, Z was 10, X (Element) was Neon. Why is the natural percent abundance 90.48%? Wouldn’t it be 50%, since number of protons and neutrons is 20? Am I just slow on understanding the process?
Thank you so much 🎉 I’m currently doing resits for A level chemistry and the question I had you had to find the % abundance of two isotopes and the bizarre thing is IT SHOWED YOU HOW TO DO IT ON THE POWERPOINT 😂 But it literally seemed like gibberish to me but seeing you explain it made it a lot make a lot more sense and I was able to follow along and get the answers that they did also provide on the PowerPoint but I needed to make sure we’re correct I’ll definitely be saving this video in case I need it in the future Thank you 🙏😊
What to do if there r three isotopes with their atomic masses and relative atomic masses given only? I tried searching the internet for some answers but they didn’t work as I thought
Why abundance is in percentage, more specifically I mean if I take total abundance to be one; abundance of 1st isotope is x then abundance of second isotope is (1-x), why to take percentage...🤔🤔🤔🤔🤔🤔
I’m not kidding if I start a skincare brand (my dream job) because I get good grades in chem (because of you) I will literally invite you to my opening or something. Oh and you get free products for life :)
Consider element Y having an atomic mass of 14.0 with 3 naturally occurring isotopes with masses 10.0, 20.0, and 30.0. If the relative abundance of Y-20 is twice as much as the abundance of Y-30, calculate the percent abundances of each isotope. (Hint: You can use elimination method) #NEEDHELP PLEASE
thanks this was helpful but what if I was only given the Mass. like they didn't tell me what the average atomic mass is only the mass and they want me to find the percentage abundance. here is the question: Naturally occurring chlorine that is put in pools has two isotopes - 35 Cl (mass = 34.969 amu) and 37 Cl (mass = 36.966 amu). Calculate the relative abundance of each isotope. how do I solve this?
@@ikilledyourgin281 If have a problem with 3 isotopes & are provided with one abundance, then the equation is set up like this "p1(1-x-y)+p2(x)+p3(y)=M" in which case you plug in the presented abundance as "y" then solve from there as simple algebra. Hope this helps!
Bro single handedly saved my g11 chem mark. thank you so much ur acc a legend ive learned more from u than everything our teacher has taught us. U acc saved my ass bro.
does anyone know how people found the percent abundance of these naturally occurring isotopes in the first place ? because i don’t think scientists are sitting down and counting which isotope each one is for every atom on earth.
Iam really interested in your video and i want to know which software you are using and annotating? It has whiteboard and options that you can change the background color and smooth writhing? Do you use digital pen?
mehrasa tarahomi it’s a smartboard it’s a few thousand dollars and I think only schools can purchase it. I believe they don’t sell to civilians, good luck finding one.
