At 20∘C, the vapour pressure of 0.1 molal aqueous solution of urea is 0.03mm less than that of water and the vapour pressure of 0.1 molal solution if KCl is 0.0594mm less than that of water. The apparent percentage dissociation of KCl in water at the given temperature is (Neglect the moles of solute particles in comparison to the moles of water in both solutions).
