The gases listed are at standard temperature and pressure: · 1 mol of co2 gas · 1 mol of n2 gas · 2 mol of o2 gas which statement is correct? the volume of 1 mol of co2 is greater than that of 2 mol of o2 . the volume of 1 mol of co2 is greater than that of 1 mol of n2 . the volumes of 2 mol of o2 and 1 mol of n2 gases are the same. **the volumes of 1 mol of co2 and 1 mol of n2 gases are the same.**
