Part A
Calculate the total rotational kinetic energy of the
molecules in 1.00 mol of a diatomic gas at 300 K.
Krot = ? J
Part B
Calculate the moment of inertia of an oxygen molecule (O2) for
rotation about either the y- or z-axis shown in
Figure 18.18 in the textbook. Treat the molecule as two massive
points (representing the oxygen atoms) separated by a distance of
1.21×10?10m. The molar mass of oxygen atoms is 16.0
