Which colligative property is used to determine the molar mass of a solute?
Correct Answer: All of the listed colligative properties can be used.
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: Identify the main colligative properties. They include boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure.
Step 3: Recognize that all these properties can be used to find the molar mass of a solute by measuring how they change when a solute is added to a solvent.
Step 4: Learn that by knowing the change in a colligative property and the amount of solute, you can calculate the molar mass using specific formulas.
