A 2.550102 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 1.000L. It was determined that the volume of water needed to do this was 998.9 mL. The density of water at 20.0 C is 0.9982 g/mL. Calculate the mole fraction of glycerol in this solution. Calculate the concentration of the glycerol solution in percent by mass. Calculate the concentration of the glycerol solution in parts per million by mass.
