Question

A single water molecule has a given mass of about 2.992 x 10^-23 g  = 18.02 amu. Estimate the number of molecules of water in a sample of 4.595 g of water.

Answer 1

4.595g * 1mol/(2.992*10^-23)g = ___ mol

Answer 2

I think I would like this answer better if it were written as follows:
4.595g * 1molecule/(2.992*10^-23)g = ___ molecules
