Which colligative property is used to determine molar mass of a solute?
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: vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.
Step 3: Learn that each of these properties can be used to find the molar mass of a solute when you know the concentration and the effect on the solvent.
Step 4: Choose the appropriate formula for the colligative property you want to use. For example, use the freezing point depression formula if you are measuring how much the freezing point of a solvent decreases.
Step 5: Plug in the values you have (like the change in temperature or pressure) into the formula to calculate the molar mass of the solute.
