Chemistry - Liquid Solution Question with Solution | TestHub

The osmotic pressure $\pi$ is given by the formula:

$\pi =CRT$

Here, $C=0.01$ M, $T=25^{\circ }\text{C}=298$ K, and $R=0.0821$ L atm mol${}^{-1}$ K${}^{-1}$.

$\pi =0.01\times 0.0821\times 298$

$\pi =0.244658$ atm $\approx 0.245$ atm

Answer: $0.245$ atm
