Osmotic Pressure Calculator

Osmotic pressure is the amount of pressure required to prevent the flow of solvent across the semipermeable membrane due to the concentration difference between the solution and the pure solvent. Osmotic pressure is a colligative property of solutions. Changes in osmotic pressure depends only on the concentration of solute particles in the solution, regardless of their identity. Osmotic pressure has important practical applications in fields such as biology, food science, and chemical engineering.
