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!!
