Which contains more molecules of water, 4.55 cm3 of ice (0.917 g/cm3) at 0◦C or 4.55 cm3 of liquid water at 0◦C? 1. the ice 2. the liquid?

How many more molecules?

Answer in units of molec.

I know its the liquad water but how do I find how many more molecules there are

I did:

m/v=d for ice and liquad water

ice mass = 0.9175 = 4.585

liquad water mass =.99985 = 4.995

then subtracted 4.995-4.585 =.41 and converted g to mol =.02277*6.022x10^23 = 1.3716E22 but its wrong!

As for me, I think the ice and the liquid will have the same number of molecules. They are the same substance but with different phase and according to the law of conservation of mass, mass cannot be created so they should the same number of molecules. Hope this answers the question.
