Question
4. What is the osmotic pressure of a solution if 1.50 grams of BaCk has been mixed in a 200mL of
0.50M solution of BaCl2? The temperature of the solution is 45°C.
5. What is the vapor pressure lowering of the resulting solution in problem 4 if the vapor pressure of the
solvent is 5.00 atm? Assume that the volume of the solvent is the volume of the solution.
6. A student was requested to prepare a 500mL of 0.5N solution of MgSO.. The lab teacher required the
student to change the concentration of the solution by adding 2.50 grams of MgSO. The boiling point
of water was determined to be 98.5°C while the freezing point was noted at 0.50 °C. What is the final
concentration of the solution expressed as molality (m) after adding extra MgS0.7 What is the boiling
point and freezing point of the solution?
(Use the Ko and Ki values from any reference.)
Assume that the volume of the solvent is also the volume of the solution.
