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 . Part A: Calculate the molality of the glycerol solution. Part B: Calculate the mole fraction of glycerol in this solution. Part C:Calculate the concentration of the glycerol solution in percent by mass. Part D: Calculate the concentration of the glycerol solution in parts per million by mass.
