What is the ratio of molar volumes of `SO_(2) and SO_(3)` ?

One mole of an ideal gas at standard temperature and pressure occupies 22.4 L (molar volume). What is the ratio of molar volume to the atomic volume of a mole of hydrogen ? (Take the size of hydrogen molecule to be about 1 overset@A ). Why is this ratio so large ?
