a.) Assuming that aqueous mannitol solutions behave ideally, calculate the vapor-pressure lowering for the above solution at 20o C.

b.) The observed vapor-pressure lowering of the mannitol solution above is 0.0930 torr. Calculate the activity coefficient ( based on mole fraction ) of water in this solution.

c.) Calculate the osmotic pressure of the mannitol solution of part ( b ) when it is measured against pure water, and compare it with the osmotic pressure of the ideal solution.
