A 2. 350×10−2 m solution of glycerol (c3h8o3) in water is at 20. 0∘c. The sample was created by dissolving a sample of c3h8o3 in water and then bringing the volume up to 1. 000 l. It was determined that the volume of water needed to do this was 999. 0 ml. The density of water at 20. 0∘c is 0. 9982 g/ml.
