Glycerol, {rm{C}}_3 {rm{H}}_8 {rm{O}}_3, is a substance used extensively in the manufacture of cosmetics, foodstuffs, antifreeze, and plastics. Glycerol is a water-soluble liquid with a density of 1.2656 {rm g/ mL} at 15 ^circ {rm C}.
Calculate the molarity of a solution of glycerol made by dissolving 66.000 mL glycerol at 15 ^circ {rm C} in enough water to make 400.00 mL of solution.
