Same osmotic pressure

Vedclass · Answer

(C) 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.For $0.2 \ M$ urea: $\pi_1 = 0.2 	imes RT$.For $0.2 \ M$ glucose: $\pi_2 = 0.2 	imes RT$.When equal volumes $(V)$ of these two solutions are mixed,the new concentration $C_{mix}$ is calculated as:$C_{mix} = \frac{C_1 V + C_2 V}{V + V} = \frac{0.2 V + 0.2 V}{2V} = 0.2 \ M$.Therefore,the osmotic pressure of the mixture is $\pi_{mix} = 0.2 	imes RT$,which is the same as the osmotic pressure of the individual solutions.

Equal volumes of $0.2 \ M$ urea and $0.2 \ M$ glucose are mixed. The mixture will have
