Glycerin (C3H8O3) is a nonvolatile nonelectrolyte with a density of 1.26 g/ml at 25 deg C. Calculate the vapor pressure at 25 deg C of a solution made by adding 50.0 mL of glycerin to 500.0 mL of water. The vapor pressure of pure water at 25 deg C is 23.8 torr.
1. An aqueous solution freezes at -0.010 deg C. What would be the osmotic
pressure at this temperature? Assume that the density of the solution is 1.00 g/ml.
2. Glycerin (C3H8O3) is a nonvolatile nonelectrolyte with a density of 1.26 g/ml at 25 deg C. Calculate the vapor pressure at 25 deg C of a solution made by adding 50.0 mL of glycerin to 500.0 mL of water. The vapor pressure of pure water at 25 deg C is 23.8 torr.
3 The vapor pressure of pure water at 110 deg C is 1070 torr. A solution of ethylene glycol, and water has a vapor pressure of 1.00 atm at 110 deg C. Assuming that Raoult’s Law is obeyed, what is the mole fraction of ethylene gycol in the solution?
