# Henry's gas law calculator

Henry's gas law postulates that at constant temperature there is a direct proportionality of the amount of gas that can be dissolved in a given volume and type of liquid to the partial pressure of the gas in equilibrium with the solvent. The constant of proportionality is called Henry's law constant and depends on the type of gas, type of liquid and temperature. Henry's gas law wiki article
