Question

In crude model of a rotating diatomic molecule of chlorine (Cl2), the two Cl atoms are2.0 cross times 10 to the power of negative 10 end exponent straight m  apart and rotate about their centre of mass with angular speed omega equals 2.0 cross times 10 to the power of 12 rad divided by straight s.  What is the rotational kinetic energy of one molecule of Cl2, which has a molar mass of 70.0g/mol?

  1. 2.32 cross times 10 to the power of negative 21 end exponent J
  2. 2.32 cross times 10 to the power of 21 straight J
  3. 2.32 cross times 10 to the power of negative 21 end exponent erg
  4. 2.32 cross times 10 to the power of 21 erg

The correct answer is: 2.32 cross times 10 to the power of negative 21 end exponent J
