1) From the formula, and a periodic table with atomic weights, determine the molecular weight of the molecule or ion under discussion.
2) Recognize that a mole is a number of grams equal to that molecular weight, or a kilomole is that number of kilograms.
For example, oxygen, specifically O2 has a a molecular weight of about 32 u (using rounded numbers), so 32 g = 1 mol,
or 32 kg = 1 kmol. But for ozone, which is an O3 molecule, it would be 48.
