Answer
-1.86 C and 100.51 C
Work Step by Step
Use conversion factors to compute the molality of the solution.
Compute the magnitude of the freezing-point depression.
Compute the magnitude of the boiling-point elevation.
Compute the freezing point of the solution by subtracting the magnitude of the freezing-point depression from the freezing point of the pure solvent.
Compute the boiling point of the solution by adding the magnitude of the boiling-point elevation to the freezing point of the pure solvent.
