Calculate the number of degrees of freedom of molecules of hydrogen in 1 cc of hydrogen gas at NTP.
hydrogen molecule is diatomic so it has 3 translational degree of freedom and 2 rotational. So degree of freedom in H2 molecule =3+2=5 for number of molecule in 1cc 22.4lit=22400cc H2 gas at STP has =6.023×1023 molecule 1cc H2 gas at STP has =224006.023×1023 molecule =2.688×1019 so total degree of freedom =5×2.688×1019 =13.440×1019=1.344×1020
