Dissolved gas

Solubility of gases

where ${\displaystyle k_{\rm {H}}}$ is a temperature-dependent constant (for example, 769.2 L·atm/mol for dioxygen (O₂) in water at 298 K), ${\displaystyle p}$ is the partial pressure (in atm), and ${\displaystyle c}$ is the concentration of the dissolved gas in the liquid (in mol/L).
