. 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). Why is this ratio so large ?
Best Answer
Explanation:-
- Size of hydrogen molecule =1Aº
- Radius of hydrogen atom=0.5 Aº
- Volume of hydrogen atoms assuming a perfect sphere is
- Gasses have large interatomic separation so their is a lot of empty space
and hence we get such a large value of molar volume to the atomic volume.
Final Answer:-
The ratio is 7.08×104 due to the large interatomic separation present between the gaseous atoms
