Vedclass · Answer

(A) The osmotic pressure $\Pi$ is given by the formula $\Pi = CRT$,where $C$ is the molar concentration,$R$ is the gas constant,and $T$ is the temperature.Since the mass of solute $(10 \ g)$ and the volume of solvent $(250 \ mL)$ are the same for all solutions,the molar concentration $C = \frac{n}{V} = \frac{mass}{M_{w} 	imes V}$ is inversely proportional to the molar mass $(M_{w})$ of the solute.Therefore,$\Pi \propto \frac{1}{M_{w}}$.Calculating molar masses:Glucose $(C_{6}H_{12}O_{6})$: $M_{w1} = 180 \ g/mol$Urea $(CH_{4}N_{2}O)$: $M_{w2} = 60 \ g/mol$Sucrose $(C_{12}H_{22}O_{11})$: $M_{w3} = 342 \ g/mol$Since $M_{w2}  P_{1} > P_{3}$.
