The units of Henry’s law constant are

Dalton’s Law OF Partial Pressure||Amagat’s law||Vapour Pressure|| Relative Humidity

Applying Henry's law: At 1.0 atm pressure, 24 g of acetylene (C_(2)H_(2)) dissolves in 1 L of acetone. If the partial pressure of acetylene is increased to 12 atm , what is the solubility in acetone? Strategy: Let S_(1) be the solubility of the gas at partical pressure P_(1) , and let S_(2) be the solubility at partial pressure P_(2) . Writing Henry's law for both pressure, we have S_(1)=KP_(1) S_(2)=KP_(2) Dividing the second equation by the first, we get S_(2)/S_(1)=(KP_(2))/(KP_(1)) or S_(2)/S_(1)=P_(2)/P_(1) we can use this relation to find the solubility at one pressure given the solubility at another.
