Question
The osmotic pressure of a dilute solution of KNO3 (i factor = 1.8) in water is 0.4697 atm when measured against water at 25 deg C. What would be the
a. vapor pressure at 25 deg. C (the partial vapor pressure of water is 23.756 mmHg at this temperature) of the solution and vapor pressure lowering
b. boiling point of the solution (Kb = 0.512) and boiling point elevation
c. freezing point of the solution (Kf = 1.86) and freezing point depression
reminder:
- Molarity will be equal to molality at 25 deg. C since it is an aqueous solution.
- 1 atm = 760 mmHg
- Rounding off: 2 decimal places in ALL OF YOUR ANSWERS
Answers:
Molality: ___ moles/L
VP lowering: ___ mmHg
VP solution: ___ mmHg
Boiling point elevation: ___ deg. C
Boiling point solution: ___ deg. C
Freezing point depression: ___ deg. C
Freezing point solution: ___ deg. C
