State the formula for osmotic pressure and provide examples.

(N/A) The formula for osmotic pressure $(\pi)$ is given by: $\pi = CRT$.
Here,$C$ is the molar concentration of the solution,$R$ is the gas constant,and $T$ is the temperature in Kelvin.
Examples of osmotic pressure include:
$1$. Preservation of food using salt or sugar solutions.
$2$. Flow of water into plant roots.
$3$. Hemolysis of red blood cells in hypotonic solutions.
