An oxygen molecule has a mass of `5.30xx10^(-26)` kg and a moment of inertia of `1.94xx10^(-46)kgm^2` about an axis through its centre perpendicular to the lines joining the two atoms. Suppose the mean speed of such a molecule in a gas is `500ms^(-1)` and that its kinetic energy of rotation is two thirds of its kinetic energy of translation Find the average angular velocity of the molecule.
