So I had a problem with wrapping my head around this question, mainly because I never really considered what mol actually means, I just did the calculations. I think I have it now, but just to confirm:

1 mol is basically 6.022x10^23 particles.
So since 0.0195 mol of carbon is present, this means there are (x) amount of particles of carbon in this sample. Since there are 22 carbon atoms in each MOLECULE, if we divide 0.0195 by 22 we get... the amount of molecules? and then to work out nitrogen, we x 6 to get amount of nitrogen atoms (because there are 6 nitrogen atoms for every molecule). Once we have done this, we can use mol mass mr formula to work out mass of nitrogen.. correct?


thanks for any help
