COLLIGATIVE PROPERTIES 1. Calculate the vapor pressure when 10.o mL glycerol (C3H8O3) is added to 500.0 mL water at 500C. At this temperature the vapor pressure of pure water is 92.5 torr and its density is 0.988 g/mL. Density of glycerol is 1.26 g/mL. 2. Calculate the boiling point and freezing point of the solution if 1.00 kg of ethylene glycol (C2H6O2) is added to a car radiator which contains 4450 g water. a. Kb of water = 0.512 oC/m at normal boiling point of 100oC b. Kf of water
