One mole of an ideal gas at standard tem...

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 1Å). Why is this ratio so large ?

Text Solution

Verified by Experts

`~= 10^(4)` , intermolecular separation in a gas is much larger than the size of a molecule.
