Web14 apr. 2016 · 2. Henry's law is usually expressed using molar concentrations, which makes more sense, because the partial pressure is proportional to activity of the solute, strictly speaking. But as long as you stay at low concentations, you could use any measure, vol-%, mol/kg, g/l, etc., Henry's law will still work acurately. Web18 jun. 2014 · The concentration of a gas dissolved in a liquid is proportional to its partial pressure above that liquid and Henry's law constant (H, M/atm). Here H refers by default to the effective Henry's law constant, which includes the hydration process. H depends mainly on the type and number of functional groups that are attached to the carbon chain. share article on facebook https://wackerlycpa.com
