Relative decrease in vapor pressure is 0.4 for a solution containing 1 mole AB in 3 mol $H_{2} O$ , therefore AB is ionised at the extent(percentage) of:

Q. Addition of a non-volatile solute to a solvent always increases the colligative property such as

π, \frac{Δ P}{P^{\circ}}, Δ T_{b}

and

Δ T_{f}

. All these colligative properties are directly proportional to the molality. The increase in colligative properties is due to increase in number of solute particles.
