Calculate the total number of degree of freedom for a mole of diatomic gas at STP.

Explanation

At S.T.P, number of degrees of freedom of a diatomic molecule = 5
Number of molecules in one mole = ` 6.02 xx 10^(23)`
`:.` total number of degrees of freedom
`= 5 xx 6.02 xx 10^(23) = 30.10 xx 10^(23)`.
