I know what is similar is that it is 6.2times10^23 of the units and that it is different in that 1 is copper and 1 is water and one is atoms and 1 is molecules, so the copper makes up a certain number of molecules that are less than a mole while the water is a mole in itself. Is there anything else you can think of?
