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 Note: 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 must be in numbers or numerical form and not in words. If you have negative answers just include the negative sign with your answer without space (Example: -11.11] Find: the BLANKS Molality: Blank 1 moles/L VP lowering: Blank 2 mmHg VP solution: Blank 3 mmHg Boiling point elevation: Blank 4 deg.C Boiling point solution: Blank 5 deg. C Freezing point depression: Blank 6 deg. C Freezing point solution: Blank 7 deg. C
