The freezing point of an aqueous solution which contains $5\%$ by mass urea,$1.0\%$ by mass $KCl$,and $10\%$ by mass glucose is ........ $K$. $\left( K_f(H_2O) = 1.86 \ K \ kg \ mol^{-1} \right)$

Find the expected value of $\Delta T_{b}$ for $1 \ m \ AlCl_3$ solution in water if a solution of a nonelectrolyte of the same concentration has a $\Delta T_{b}$ value of '$x$' $K$.

If the $O.P.$ (Osmotic Pressure) of $1 \ M$ solutions of the following compounds in water can be measured,which one will show the maximum $O.P.$?

What is the expected value of $\Delta T_f$ for $1.25 \ m$ $CaCl_2$ solution if $1.25 \ m$ sucrose solution has $\Delta T_f$ value $x \ K$?

$AB_2$ is $10\%$ dissociated in water to $A^{2+}$ and $B^{-}$. The boiling point of a $10.0 \text{ molal}$ aqueous solution of $AB_2$ is . . . . . . $^\circ C$. (Round off to the Nearest Integer). [Given: Molal elevation constant of water $K_b = 0.5 \text{ K kg mol}^{-1}$,boiling point of pure water $= 100^\circ C$]
