   Vessel-1 contains ${\mathbf{w}}_2$ g of a non-volatile solute $\mathbf{X}$ dissolved in ${\mathbf{w}}_1$ g of water. Vessel-2 contains ${\mathbf{w}}_2$ g of another non-volatile solute $\mathbf{Y}$ dissolved in ${\mathbf{w}}_1$ g of water. Both the vessels are at the same temperature and pressure. The molar mass of $\mathbf{X}$ is 80% of that of $\mathbf{Y}$. The van’t Hoff factor for $\mathbf{X}$ is 1.2 times of that of $\mathbf{Y}$ for their respective concentrations. The elevation of boiling point for solution in Vessel-1 is ____ % of the solution in Vessel-2.
