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

Explanation:

I could ask the same question question using "dozens"dozens in place of "moles"moles. I have 3636 C_6H_12O_6C6H12O6 molecules or "3 dozen"3 dozen sugar molecules.....clearly I have

....(6xx36*"oxygen atoms")/(12*"oxygen atoms"*"dozen"^-1)6×36oxygen atoms12oxygen atomsdozen1

=18*"dozen"*"oxygen atoms"=18dozenoxygen atoms

And in the question, we replace "dozen"dozen with "mole"mole, where 1*mol-=6.022xx10^231mol6.022×1023 individual items.....

What is the mass of this quantity of oxygen atoms?
