If I understood your question, the relationship between 32grams of O_2, Avogadro's number and 1 mole can be described briefly like this:

A very good analogy for the concept of mole is that one can think of a mole as a "chemist's dozen"; instead of going by the number of individual atoms or molecules that form a certain amount of a substance, one would use moles, where

1 mole has 6.022 * 10^23 atoms

Now, molar mass represents the weight of one mole of a certain element or substance; 1 mole of oxygen weighs approximately 16 grams, which would mean that 1 mole of diatomic oxygen, O_2, weighs twice than that, 32 grams.

So, 32grams of O_2 represents 1 mole, which in turn represents 6.022 * 10^23 O_2 molecules.
