Henry’s law Calculator

The Henry’s law constant ($k$) can also be expressed as the ratio of the concentration of the gas in the liquid phase to the partial pressure of the gas in the gas phase at equilibrium, at a specific temperature.

Where:

• $C$ is the concentration of the gas in the liquid (usually in mol/L or mmol/L),
• $k$ is Henry’s law constant, which is specific to the solute-solvent pair and is often temperature-dependent,
• $P$ is the partial pressure of the gas above the liquid (usually in atm or mmHg).
