I'm not a student per se, but ever since i've come across quantum theory, i've been pretty much obsessed with learning near everything. I'm seeing how one can use Avogadro's Principle to determine molecular masses of gasses and such. This could be a stupid question but, WHY is it, that equal volumes of any gas at STP conditions contain the same amount of molecules?
@lilmissfame1000 It's the atomic mass of c2h4. Carbon is 12 AMU, and Hydrogen is 4 AMU. 2 carbon equals 24 and 4 hydrogen is 4 AMU. Add them up and get 28 AMU. AMU is equal to grams. There is always 6.02x10^23 molecules.
I have a feeling that my question below may be to the likes of another question i've had since several months ago that I could not find an answer for. The responses were more - "we don't know, it's just how it is...", and I just can't accept that! Anyways, the below may be like my question, WHY can there only be up to two electrons in the first energy shell of any atom, instead of 3 or more? To me that says something about the electron, that it has a universe constant to it, such as an amplitude
No Avogadro didn't come up with that number. He just said equal number. The French scientist who came up with that number won a Nobel Prize for his efforts.
first 20 seconds was a great summery of what Avogadro's Principle

use PV = nRT and the combined gas law (P1V1/T1 = P2V2/T2)

I'm eager for Reger, and mildly excited for brightstorm.
um where did you get the 28 grams from ????
I need help with equations when the conditions are NOT at STP! That's what I don't get. :(
Congratulations!! I'm from Romanian! Here , teachers don't do the lessons so explicit ! I must to watch on youtube, when I want to learn something!.
she said that 28g is the molar mass of ethylene

In standard conditions iodine is solid.

I really like Avocado's principle
@stardreamer79 she plainly said 1000 @ 2:46...
3:20 you could just continue without calculating the molar mass of C2H4 :/ :D
YOU ARE WONDERFULL!
thnx a lot teacher i will subscribe right nw,bcoz dis video helps me a lot
Yes
I thought Iodine was a liquid
Am I the first to notice this?
You're Really cute!
