What it calculates

The “Osmotic Pressure” calculator computes π in atm from 3 parameters: molarity (mol/L), t, k, i (van't hoff).

A standard physics formula used in educational and engineering tasks.

Example calculation

With parameters Molarity = 0.5 mol/L, T, K = 298, i (van't Hoff) = 1 the result is 12.23 atm.
