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