Concept Introduction:
In the process of osmosis, the solvent molecules pass through a semi - permeable membrane from less concentrated solution to more concentrated solution. The pressure that has to be applied to prevent the flow of solvent molecules is called osmotic pressure. It is expressed as,
π=MRT
Where,
π= osmotic pressureM= Molar concentrationR= Universal gas constantT= Temperature
Molarity or molal concentration is one of the many parameters that is used to express concentration of a solution. It is expressed as,
Molarity = number of molesof solutevolume of solution in L
