16.) An aqueous solution of a nonvolatile solute has a boiling point of 101.9°C. Calculate the freezing point of the same solution. For water Kf = 1.86°C/m (°C∙kg/mole) and Kb = 0.512°C/m (°C∙kg/mole).

Colligative properties:
The colligative properties are those properties of solutions that depend on the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the nature of the solute particles. The number ratio can be related to the molality of the solution. These properties depend on the nature of the solvent.
Colligative properties include:
Relative lowering of vapor pressure (Raoult's law)
Elevation of boiling point
Depression of freezing point
Osmotic pressure
