This chemistry video tutorial provides a basic introduction into stoichiometry. It contains mole to mole conversions, grams to grams and mole to gram dimensional analysis problems. It contains mole ratio practice problems as well as other examples. The molar ratio can be found using the cofficients of the balanced chemical equation. The conversion from moles to grams and grams to moles can be accomplished using the molar mass of the substance.

Thank you sooo much! You're a good friend of mine in my head. I appreciate you and Tyler.

Literally thank you so much 🙏 I actually understand the conversions instead of my teacher just saying use molar ratio without explaining what it was first

THANKS!! I FINALLY UNDERSTAND IT..!!!

Him: “as you can see, it’s not that hard to conver- “ Me: * *has tears literally running down my cheeks* *🥲 I need someone to explain this to me as if I am a literal toddler. Like I’m so serious, I’m crying right now because I don’t understand this and I have an assignment to tomorrow that’s being taken as a test grade. SOMEONE PLEASE HELP. SOS 😭😭✋

If you still need help, I didn't understand either, but go through the part of the video you need slowly. Take frequent pauses to Type or Draw the progress out. Keep a Periodic Table open. Take your time.

Well, this is probably late, but for here’s (a). You want to convert the 35g of Al to g of AlCl. The excess Cl is essentially irrelevant to the conversions. To lay it out, you want to figure out a path from gAl to gAlCl. G Al - Mol Al - Mol AlCl - G AlCl, is going to be your best bet. You multiply the 35g Al to 1mol Al/26.98g Al to find the moles of Al present in the equation. That’s pretty much dividing 35 (gAl) by 26.98 (atomic mass of Al). You do this because you have 35g of Al, but the conversion factor for grams to moles is what you want (1 Mol) per what you have (which has to be different than what you’re given). Then you multiply the result of that equation (~1.3) by the mole proportion of AlCl3 to Al to shift from using Al to AlCl3. In the equation, the proportion is 2:3:2, with the 2 corresponding to Al and AlCl3. Because 2/2 = 1 you just multiply 1.3 by one to find the moles of AlCl3. The final step is multiplying the 1.3 by the molar mass of AlCl3 (133.333g [found from adding the atomic masses of each element in its quantities of atoms [[1 atom of Al, 3 atoms of Cl]]) over 1 mole of AlCl3 (“grams per mole” (singular)). That gets you an answer of about 172.96 gAlCl3. For the next one you do essentially the same thing, ignoring the “completely” part (or at least I did that, because it confused me).

excellent!!! my teacher spent 4 weeks teaching us and this man taught me in 25minutes thank you, man.

@eduarddanilyan1892 4 года назад

I am a 13 year old and because of how thorough he is explaining this, I can easily understand it even though this chemistry is probably for high school and/or college. Thank you very much for making these videos. Keep up the good work. You are the best!

pov: you were kinda but also kinda not paying attention during chem and did your worksheets with the help of the internet OwO now you have a test but you dont feel like cheating on the test because you actually need to understand how to do this stuff for AP Chem

@juliirias7437 3 года назад

you are a amazing, literally if every teacher was like you, everyone would dominate the subject! thank you soooooooo much!

Bro, this man is a universal legend. I just started stoichiometry yesterday from his videos and I thought that these concepts would be like on whole another difficulty level but they were a piece of cake > thanks to him. Hats off to youtubers like this who are teaching concepts (worth 1 week of teaching) in about 23 minutes and there are more great videos with detailed explanation of stoichiometry & other science concepts. He's the Science Teacher everyone deserves. ☺☺
