The total number of degrees of freedom of molecules of hydrogen of volume 1 cc  at NTP is 1.34×10(5×N). Find N.

1 mole of hydrogen at NTP occupies 22.4 litres.Therefore, number of moles in 1 cc of hydrogen at NTP = 122.4×10001=4.46×10−5 Number of molecules of Hydrogen =  4.46×10−56.023×1023=26.86×1018Each hydrogen molecule has 5 degrees of freedom.So, total number of degrees of freedom =  5×26.86×1018=1.34×1020
