"Number of moles" = "Mass"/"Molar mass" ~= 0.02*mol

Explanation:

And thus, (0.34*cancelg)/(18.01*cancelg*mol^-1) = (??)/(mol^-1) = ??mol

Note that all I have done here is set up the problem dimensionally. I want an answer in moles, and it seems I got an answer in moles, which makes me think that I have done it right. How many water molecules in such a quantity?
