H = 1 * 2 = 2
O = 16
16 + 2 =18

The molecular mass of water is 18.0153 g/mol
The density of water is 997.07 g/L at 25 C.
The molarity of water is therefore:
(997.07 g/L) x (18.0153 g/mol) = 55.346 mol/L
or = 55.346 M
Best wishes and good luck

molarity of pure water is displaced volume of solute /moleculer weight of solution(/L). infact molarity of water is55.4

pure water weights 1kg = 1000g/l
The molecular weight of water is 18g (H2O = 2*1+16=18)
so divide 1000/18 = 55.5 moles/liter

The molecular mass of water is 18.0153 g/mol, and the density of water is
997.07 g/L at 25 C. That makes
(997.07 g/L)(mol/18.0153 g) = 55.346 mol/L.
