1 mol $O_2$ has the greater number of atoms.

Work Step by Step

1 molecule $O_2$: - 2 Oxygen atoms. 1 mol $O_2$: $6.022 \times 10^{23}$ $O_2$ molecules; Each $O_2$ molecule has 2 atoms: Which means: $6.022 \times 10^{23} * 2 = 1.2044 \times 10^{24}$ atoms. This is more than $6.022 \times 10^{23}$. Thus, 1 mol $O_2$ has the greater number of atoms.
