Vessel-1 contains w ₂ ~g of a non-volatile solute X dissolved in w ₁ ~g of water. Vessel- 2 contains w ₂ ~g of another non-volatile solute Y dissolved in w ₁ ~g of water. Both the vessels are at the same temperature and pressure. The molar mass of X is 80 % of that of Y . The van't Hoff factor for X is 1.2 times of that of Y for their respective concentrations. The elevation of boiling point for solution in Vessel-1
