Question
A flask P contains 0.5 mole of oxygen gas and other flask Q contains 0.4 moles of ozone gas. Which flask has larger oxygen atoms?

Answer
I think you mean the larger NUMBER of oxygen atoms

oxygen gas is O2, ozone is O3

0.5 mole O2 X 6.02x10^23 molecules/mole X 2 atoms/molecule = 6.02x10^23 atoms O

0.4 mole O3 X 6.02x10^23 molecules/mole X 3 atoms/molecule = 7.22x10^23 atoms O

So the O3 sample has more atoms of O
