    This is a short answer type question as classified in NCERT Exemplar

    Volume occupied by 1 mole = 1mole of the gas at NTP= 22400mL=22400cc

    So number of molecules in 1cc of hydrogen= 6.023 × 10 23 22400 = 2.688 × 10 19

    H2 is a diatomic gas, having a total of 5 degrees of freedom

    So total degrees possesed by all the molecules

    = 5 × 2.688 × 10 19 = 1.344 × 10 20
