Question

Consider a sample of oxygen behaving like an ideal gas. At 300 K, the ratio of root mean square (rms) velocity to the average velocity of gas molecule would be :

(Molecular weight of oxygen is 32g/mol; R = 8.3 J K^$-$1 mol^$-$1)

$\sqrt {{{3\pi } \over 8}} $

$\sqrt {{3 \over 3}} $

$\sqrt {{8 \over 3}} $
