Find the number of moles in 3.4 x 10^14 molecules of water?
it should be just that 3.4x10^14 times Avagadro's number(6.02 x 10^23)
I think that you should divide 3.4e14 by Avogadro's number(N) since N is the number of molecules per mole of a substance. Multiplying will give an astronomically large number.
