Well, 18 moles......with respect to dioxygen...

Explanation:

I could ask the same question question using "dozens" in place of "moles". I have 36 C_6H_12O_6 molecules or "3 dozen" sugar molecules.....clearly I have

....(6xx36*"oxygen atoms")/(12*"oxygen atoms"*"dozen"^-1)

=18*"dozen"*"oxygen atoms"

And in the question, we replace "dozen" with "mole", where 1*mol-=6.022xx10^23 individual items.....

What is the mass of this quantity of oxygen atoms?
