The gases listed are at standard temperature and pressure:· 1 mol of CO2 gas· 1 mol of N2 gas· 2 mol of O2 gasWhich statement is correct?

At the same temperature and pressure, equal numbers of moles of ideal gases occupy equal volumes (Avogadro’s law). Therefore, 1 mol of CO2 and 1 mol of N2 have the same volume. Two moles of O2 occupy twice the volume of either one-mole sample.
