      (Hint: Use the density and molar mass of water.) What happens to the concentration of water when a solute is dissolved in it? (1000 g/L) / 18.0 g/mol = 55.6 mol/L. The concentration of water decreases as a the concentration of a solute increases because the solute occupies some of the volume and the water molecules are pushed apart. 4
