Dear Yash
 
We know that at NTP condition
 
22.4 lts = 2.4 × 103 cm3 of any gas contains 6.023 × 1023 molecules
 
∴ Number of molecules in 1 cm3 of H2 gas = 6.023 * 10^23  / 22400
  = 0.26875 × 1020
  Number of degrees of freedom of a H2 gas molecule is 5
  ∴ Total number of degrees of freedom of 0.26875 × 1020 molecules =0.26875 × 1020 × 5
    =1.34375 × 1020
