  • um where did you get the 28 grams from ????

  • @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.

  • is 1 kg equals to 100 grams? not 1000

    grams?

  • @stardreamer79 she plainly said 1000 @ 2:46...

  • I noe this really helps man

  • thnx a lot teacher i will subscribe right nw,bcoz dis video helps me a lot

  • 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

  • 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?

  • You are the best teacher thank you.

  • YOU ARE WONDERFULL!

  • zzzzzzzzz

  • thanks alot.... im downloading each & every video
