Oh well, I just answer the chemistry here, but please post it in the chemistry section next time.

A mol is just a number, like a dozen. So we need to know the "value" of a mol, to this we have Avogadro's number which gives the "value". The number is.
$\Large N_{A}=6.02214 \times 10^{23} mol^{-1}$
If you do this for methane you know how many methane molecules we have. If you multiply with the amount of atoms in methane we get the total amount of atoms.
