In a crude model of a rotating diatomic molecule of chlorine (Cl2), the two Cl atoms are 2.00 multiplied by 10-10 m apart and rotate about their center of mass with angular speed ? = 1.00 multiplied by 1012 rad/s. What is the rotational kinetic energy of one molecule of Cl2, which has a molar mass of 70.0 g/mol.
