Real-Time Gas Solubility Calculations
At 25°C and 1.0 atm partial pressure, the solubility of Oxygen in water is 0.0013 mol/L.
This advanced Henry's Law calculator includes:
C = kH × P
Where:
C = Concentration of dissolved gas (mol/L)
kH = Henry's Law constant (mol/L·atm)
P = Partial pressure of the gas (atm)

Henry's Law is a fundamental principle in physical chemistry that describes the relationship between the amount of gas dissolved in a liquid and the partial pressure of that gas above the liquid. This article will help you understand how to use our Henry's Law Calculator effectively and apply it to real-world scenarios.
Henry's Law states that at a constant temperature, the amount of gas dissolved in a liquid is directly proportional to the partial pressure of that gas in equilibrium with the liquid. The mathematical expression is:
