उत्तर
In calculating osmotic pressure the concentration of solute is expressed in molarity.
Explanation:
The pressure difference required to block the flow of solvent across a semipermeable membrane from low concentration solution to high concentration solution is referred to as the osmotic pressure of a solution. In morality, the osmotic pressure of a solution is proportional to the molar concentration.
