Gas is N2O4.
fill in the chart. I've got all but atoms.

how do I get the # of atoms?
why wouldn't it be the same as molecules:
1 mol/22.4L * 6.02x10^23 molecules/1 mol * 5.02L
= 1.35x10^23 molecules
molecules of are: 1.35x10^23
why couldn't I just replace the word 'molecules' with atoms
ie, 6.02x10^23 atoms in the above conversion and get
the same answer?

molecules: 1.35x10^23
Atoms: ??? how do you set this up?
Mass: 20.6g
Vol at STP: 5.02L

answer from book is 8.10x10^23 atoms

1 molecule of N2O4 contains 6 atoms (assume that all of the bonds are covalent).

6 * Your Answer = Their Answer
