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= 0.917*5= 4.585
liquad water mass= .9998*5= 4.995

then subtracted 4.995-4.585= .41 and converted g to mol= .02277*6.022x10^23= 1.3716e22 but its
