Solution X is unsaturated so v.p. will be more, solution Y and Z are saturated so v.p. of Y= v.p. of Z and 2 g of solute would be present in form of solid in system Z.

Q. The solubility of a specific non-volatile salt is $4 g$ in $100 g$ of water at $2 5^{\circ} C$ . If $2.0 g ., 4.0 g$ and $6.0 g$ of the salt added to $100 g$ of water at $2 5^{\circ} C$ , in system $X, Y$ and $Z$ . The vapour pressure would be in the order:

$X < Y < Z$

$X > Y > Z$

$Z > X = Y$

$X > Y = Z$

Solution $X$ is unsaturated so v.p. will be more, solution $Y$ and $Z$ are saturated so v.p. of $Y =$ v.p. of $Z$ and $2 g$ of solute would be present in form of solid in system $Z$ .

Q. The solubility of a specific non-volatile salt is 4g in 100g of water at 25∘C. If 2.0g.,4.0g and 6.0g of the salt added to 100g of water at 25∘C, in system X,Y and Z. The vapour pressure would be in the order:

X<Y<Z

X>Y>Z

Z>X=Y

X>Y=Z
