For the mass of a heteronuclear diatomice molecule you do it like you
did in Gen Chem.  You add up the molar masses of the individual atoms
and then divide by 1000 (if you are using SI units) and then divide by
Avogadro's number to get the mass of a single molecule.

The rotational and vibrational temperatures are in Table 16.2.   If,
however, they were not there you could calculate them using
spectroscopic data (Table 13.4) and the appropriate equations in the
text for the characteristic temperatures (which are summarized in my
class handout).
