Questions & Step-by-Step Solutions
Which colligative property can be used to determine the 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. They include boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure.
Step 3: Recognize that each of these properties can be used to find the molar mass of a solute when a known amount of solute is dissolved in a solvent.
Step 4: Learn that by measuring how much a colligative property changes, you can calculate the number of solute particles, which helps in determining the molar mass.
