directly proportional to the concentration.

(A) The osmotic pressure $(\pi)$ of a solution is given by the van't Hoff equation: $\pi = CRT$,where $C$ is the molar concentration,$R$ is the gas constant,and $T$ is the absolute temperature.At a constant temperature $(T)$,the product $RT$ is constant.Therefore,$\pi \propto C$.This means the osmotic pressure is directly proportional to the concentration of the solution.
