In a crude model of a rotating diatomic molecule of chlorine (Cl2), the two Cl atoms are 2.00e-10 m apart and rotate about their center of mass with angular speed w = 1.40e12 rad/s. What is the rotational kinetic energy of one molecule of Cl2, which has a molar mass of 70.0 g/mol?(adsbygoogle = window.adsbygoogle || []).push({});

>> I wasn't exactly sure how to do this, so I thought I'd try with the rotational kinetic formula from the first half of General Physics. That formula was 1/2(m)(r^2)(w^2). I don't think it gave me the answer they were looking for... it wants an answer in Joules and I'm not sure where to start or how to finish it. Or if this is even along the right steps to take...
