If I buy a pair of socks, how many socks do I have? Well I have the one pair, but I do have TWO socks!

Explanation:

You specify a mole of oxygen molecules. This is a mole, Avogadro's number, of #O_2# species.

Clearly there are #2xxN_A# oxygen atoms, where #N_A="Avogadro's number", # #6.022xx10^23#.
