Executive summary:

Henry's Law states that at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.Henry’s law constant of 2 octanone was estimated to be 20.7 Pa m³/mol at 25 degC.
