The solubility of a specific non-volatile salt is 4 g in 100 g of water at $25^{\circ} \mathrm{C}$.

Question

The solubility of a specific non-volatile salt is 4 g in 100 g of water at $25^{\circ} \mathrm{C}$. If $2.0 \mathrm{~g}, 4.0 \mathrm{~g}$ and 6.0 g of the salt added of 100 g of water at $25^{\circ} \mathrm{C}$, in system $X, Y$ and $Z$. The vapour pressure would be in the order:

(d) Solution $X$ is unsaturated so v.p. will be more, solution $Y$ and $Z$ are saturated so v.p. of $Y=\mathrm{v} . \mathrm{p}$. of $Z$ and 2 gm of solute would be present in form of solid in system $Z$.
