Question: Which of the following colligative properties is used to determine the molar mass of a solute?

Options:

Correct Answer: Freezing point depression

Solution:

Freezing point depression can be used to determine the molar mass of a solute by measuring the decrease in freezing point.

Which of the following colligative properties is used to determine the molar mass of a solute?

Correct Answer: Freezing point depression

Step 1: Understand what colligative properties are. These are properties that depend on the number of solute particles in a solution, not the type of particles.
Step 2: Learn about freezing point depression. This is when the freezing point of a solvent decreases when a solute is added.
Step 3: Know that by measuring how much the freezing point decreases, you can find out how many solute particles are in the solution.
Step 4: Use the formula for freezing point depression, which relates the change in freezing point to the molality of the solution and the molal freezing point depression constant.
Step 5: Rearrange the formula to solve for the molar mass of the solute using the measured freezing point depression.
