According to Raoult's law mole fraction of solute in solution is given by formula

Options

  1. AP P ₁^0
  2. BP ₁^0 P ₁
  3. CP ₁^0 P
  4. DP ₁ P ₁^0

Correct answer

A. P P ₁^0

Step-by-step solution

P₁= Vapour pressure of solution P ₁^0= Vapour pressure of pure solvent Mole fraction of solute = P ₁^0- P ₁ P ₁^0 = P P ₁^0
