Colligative Properties. A solution was prepared by dissolving 2.50 g of MgCl2 (MM: 95.21
g/mol) in 150.00 g of solvent X. It was determined that the boiling point of this solution was
0.50°C higher than the normal boiling point of the pure solvent X. (8 points)
a. Assuming that the solution is ideally dilute, what is the van’t Hoff factor? (2 points)
b. What is the molal concentration of the solute in the solution? (2 points)
c. What is the Kb of solvent X? (2 points)
d. If the freezing point of pure solvent is -4.53°C and Kf = 3.25°C/m, what is the freezing
point (in °C) of the solution? (2 points)
