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?
