Osmotic pressure - is the difference in the pressure between two solutions that prevent fluid flow through semi-permeable membrane [1]

Osmotic pressure occurs when two solutions separated by semipermeable membrane have different concentrations of solutes. According to a rule of osmosis, fluid moves from an area of low concentration of solutes to an area of high concentration [2]

Osmotic pressure can be calculated using the following formula [3]:

        ∏ = nRT/V = MMRT
