Osmotic Pressure (van ’t Hoff Formula) Calculator

Easily calculate and compute osmotic pressure (van ’t hoff formula) calculator with accurate equations, live formulas, and expert guidance.

Normal saline (0.9% NaCl) is ~0.154 M.

37°C is normal human body temperature.

NaCl dissociates into Na+ and Cl- so i = 2; Glucose does not dissociate so i = 1.
