Answer:

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?

Explanation:

#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?
