Chemistry - Liquid Solution Question with Solution | TestHub

Two sucrose solutions of same molality prepared in different solvents will not have the same freezing point depression as for both the solvents${\mathrm{K}}_{\mathrm{f}}$will be different so statement$\left(\mathrm{A}\right)$is incorrect. Rest of the statements are correct.
$\mathrm{\pi }=\mathrm{M}\mathrm{R}\mathrm{T}$, where M is the molarity of the solution so$\left(\mathrm{B}\right)$is correct
vapour pressure of a component over a solution is proportional to its mole fraction, it is Rault's law so option$\left(\mathrm{C}\right)$is also correct.
Based on ($\mathrm{m}\times \mathrm{i}$) value this order of osmotic pressure for 0.01 M aqueous solution is correct$\mathrm{B}\mathrm{a}\mathrm{C}{\mathrm{l}}_2>\mathrm{K}\mathrm{C}\mathrm{l}>\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}>\mathrm{S}\mathrm{u}\mathrm{c}\mathrm{r}\mathrm{o}\mathrm{s}\mathrm{e}$
