hi i am in AP Chemistry as a junior in high school and i have a question that i need help with it reads "a white powder is analyzed and found to contain 43.64% phosphorus and 56.36% oxygen by mass.The compound has a molar mass of 283.88 g/mol. What are the compound's empirical and molecular formula's?" i could really use any help anyone gives me because i need to know if i am doing these right i have a test tuesday over problems like this you can message me if you can help THANKS !!!
i love how this looks like this guy was just chilling in his house, and was like you know what. Ima make a video about stoichiometry. boom. thanks for the video
Dude, you are possible one of the best teachers out there, you have helped me out in chemistry so much! every time I get stuck, I look you up on youtube :D
Is this really junior chemistry? I'm a sophomore and we're learning this.... Lol. Thank you though! You helped me for my stoichiometry test I have tomorrow!
You are a wonderful person. Thankyou. So much. I've spent the last half an hour trying to understand this and I watch a four minute video and suddenly the heavens are singing.
I LOVE YOUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU
do you have a anything for gar stoichiometry? stoichiometry that deals with 22.4 L instead of finding out the numbers of moles for a substance? (hope that made sense)
Your energy is contagious, this is great! Instead of trying to learn in my classroom with a teacher who has a very monotonous put-you-to-sleep voice and huge fluorescent lights sucking the lively spirits outta everyone, I can just learn from you, on you tube :D
im good with everything in chemistry up to this! im have a very hard time getting a good understanding for it. but this helped me out alot. thank you very much for helping me pass/survive the test and not go completely insane
Why is chemistry difficult for me? I'm a physics major and I can handle the the physics, the calcs, and even diff. eq. fairly easily but when it comes to chem I just have a hard time.....
You can tell that this guy is really "stoch"ed about doing some chemistry,
hah, I really do wish you were my chemistry teacher.
