Solution and Explanation
Osmotic Pressure:
Osmotic pressure is the minimum pressure that must be applied to a solution to prevent the flow of solvent molecules into it through a semipermeable membrane.
It is a colligative property and is given by: \[ \pi = C R T \] where:
- \(\pi\) = osmotic pressure
- \(C\) = molar concentration of solute
- \(R\) = universal gas constant
- \(T\) = absolute temperature

Assume complete dissociation of NaCl
(Given : Molar mass of Na and Cl are 23 and 35.5 g mol$^{-1}$ respectively.) A substance 'X' (1.5 g) dissolved in 150 g of a solvent 'Y' (molar mass = 300 g mol$^{-1}$) led to an elevation of the boiling point by 0.5 K. The relative lowering in the vapour pressure of the solvent 'Y' is $____________ \(\times 10^{-2}\). (nearest integer)
