Well how many oxygen atoms in A DOZEN dioxygen molecules?

Explanation:

And if got #12xxO_2*"molecules"#, THERE are NECESSARILY #24*"oxygen atoms"#. With me?

Here we got #1*mol# with respect to #O_2#...and the mole is just another collective number like the dozen....EXCEPT that we know that #1*mol# of #O_2# has a mass of #32*g#...

We got one mole, i.e. #6.022xx10^23# #"dioxygen molecules"#....and thus we got #1.204xx10^24# #"oxygen atoms"#....Capisce?
