(C) Osmotic pressure $(\Pi)$ is given by the formula $\Pi = CRT = \frac{n}{V}RT = \frac{w}{M \times V}RT$. Since $w$ (mass),$V$ (volume),$R$ (gas constant),and $T$ (temperature) are constant for all three solutions,the osmotic pressure is inversely proportional to the molar mass $(M)$ of the solute: $\Pi \propto \frac{1}{M}$. The molar masses are: Urea $(NH_2CONH_2)$ = $60 \ g/mol$,Glucose $(C_6H_{12}O_6)$ = $180 \ g/mol$,and Sucrose $(C_{12}H_{22}O_{11})$ = $342 \ g/mol$. Since $60 P_1 > P_3$.
