This question is the same as if your were asked, $"how many gloves are there in 1 dozen pairs of gloves?"$
Can you answer that?

$1$ $"mole"$ of stuff specifies $"Avogadro's number, "N_A,$ $6.022xx10^23$ individual items of stuff.

Here I have $N_A xx O_2$ molecules. Clearly, there are $2xxN_A$ oxygen atoms. What is the mass of this number of oxygen atoms?
