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

Options

A. `6.02xx10^(23)`
B. `18.06xx10^(23)`
C. `30.1xx10^(23)`
D. `36.12xx10^(23)`

Answer

C

Explanation

T = 273 K
The number of degrees of freedom of one molecule of a diatomic gas is 5.
As one mole contains `6.02xx10^(23)` molecules,
`therefore` The number of degrees of freedom of `6.02xx10^(23)` molecules = `5xx6.02xx10^(23)=30.1xx10^(23)`.
