1. A solution is prepared by dissolving 0.112 g of CaCl2 in 100 g of water. The osmotic pressure of this solution is found to be 512 mmHg at 25 degrees C. Assume that the density of the solution is 1.00g/mL.
a. What is the van't Hoff factor, i, for the solution?
b. How would the value of i change as the solution becomes more concentrated? Explain.
2. Arrange these aqueous solutions, each 10% by mass in solute, in order of increasing freezing point and boiling point. Explain your reasoning.
-Glucose (C6H12O6)
-Sucrose (C12H22O11)
-Sodium nitrate
-Calcium Chloride
