Given below are two statements :
Statement I : $\displaystyle \mathrm{H}_2 \mathrm{O}$ molecules move from the chamber $\displaystyle 1$ to chamber 2.
Statement II : The osmotic pressure of a solution prepared by dissolving $\displaystyle 50$ mg of potassium sulphate (molar mass $\displaystyle =174 \mathrm{~g} / \mathrm{mol}$ ) in $\displaystyle 2$ L of water (at $\displaystyle 27^{\circ} \mathrm{C}$ ) is $\displaystyle 0.0107$ bar. (Given: $\displaystyle \mathrm{R}=0.083 \mathrm{dm}^3$ bar $\displaystyle \mathrm{K}^{-1} \mathrm{~mol}^{-1}$ and assume complete dissociation of electrolyte)In the light of the above statements, choose the correct answer from the options given below :
| Chamber $\displaystyle 1$ | Semi-permeable membrane | Chamber $\displaystyle 2$ |
| $\displaystyle 18$ g glucose in $\displaystyle 100$ mL aqueous solution | $\displaystyle 30$ g glucose in $\displaystyle 250$ mL aqueous solution |
