Worked practice questions

The relative lowering of vapour pressure of a dilute solution of a non-volatile solute equals:

  1. The mole fraction of solute
  2. The mole fraction of solvent
  3. The volume of solvent
  4. The mass of solute
Show answer and solution

Correct answer: A. The mole fraction of solute

**From Raoult:** $\Delta P / P_1^0 = (P_1^0 - P_1)/P_1^0 = x_2$ (mole fraction of solute). This is one of the four classical colligative properties.
