Question 2.17 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?

Atomic value=4/3 π R^3 × N = 4/3π (0.5 ×10^-10)^3 × 6.023 × 10^23= 3.154 × 10^-7 m^3.
Molar volume=22.4 litre=22.4×10^-3m^3
Molar volume/atomic volume=22.4×10^-3/3.154×10^-7=7.1×10^4
Molar volume=22.4 litre=22.4×10^-3m^3
Molar volume/atomic volume=22.4×10^-3/3.154×10^-7=7.1×10^4
