Partial pressure of solute in Henry's law (given mole fraction,Henry's law constant)
partial pressure of the solute in the gas above the solution
mole fraction of the solute
Henry\'s constant for mole fraction
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. For a dilute solution, the concentration of the solute is approximately proportional to its mole fraction x, and Henry's law can be written as p = kH*x.
