Vedclass · Answer

(C) The osmotic pressure $(\pi)$ of a solution is given by the formula: $\pi = CRT$. Since the temperature $(T)$ and the gas constant $(R)$ are constant,the osmotic pressure is directly proportional to the concentration $(C)$,i.e.,$\pi \propto C$. Therefore,the ratio of the osmotic pressures of the two solutions is: $\frac{\pi_1}{\pi_2} = \frac{C_1}{C_2}$. Given $C_1 = 0.01 \, M$ and $C_2 = 0.001 \, M$,the ratio is: $\frac{0.01}{0.001} = 10$. Thus,the correct option is $C$.

At $298 \, K$,the ratio of osmotic pressures of two solutions of a substance with concentrations of $0.01 \, M$ and $0.001 \, M$ respectively,is
