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. Include units. Part A: Calculate the molality of the glycerol solution. Part B: Calculate the mole fraction of glycerol in this solution....

Calculate the vapor pressure of a solution containing 36.5 g of glycerol (C3H8O3) and 125 mL of water at 30.0 °C. The vapor pressure of pure water at this temperature is 31.8 torr. Assume that glycerol is not volatile and dissolves molecularly (i.e., it is not ionic) and use a density of 1.00 g/mL for the water.
