The molarity of pure water is calculated by dividing the number of moles of water by the volume in liters. Since the density of water is 1 g/mL, 1 liter of water weighs 1000 grams. The molecular weight of water is 18 g/mol, so there are 1000/18 = 55.6 moles of water in 1 liter, making the molarity 55.6M.
