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

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

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 common 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. This is done by measuring how much the property changes when a solute is added to a solvent.
Step 4: Realize that by knowing the change in the colligative property and the amount of solute, you can calculate the molar mass using specific formulas.
