The oxygen molecule has a mass of `5.30 xx 10^(-26) kg` and a moment of inertia of `1.94 xx 10^(-46) kg m^(2)` about an axis through its centre perpendicular to the line joining the two atoms. Suppose the mean speed of such a molecule in a gas is `500 m//s` and that its kinetic energy of rotation is two thirds of its kinetic energy of translation. Find the average angular velocity of the molecule.

Explanation

`6.75xx10^(12)" rad s"^(-1)`
