A vessel with a volume of 2 L is halfâ€filled with water and thensealed so it
contains 1 L of air and 1 L of water. We will now conduct anexperiment to determine
Henry’s constant for toluene, by adding one gram of liquid toluenethrough a rubber
septum. We then shake the container and wait for equilibrium. Asample of gas is then
extracted from the head space above the water and analyzed using aGC to determine
that the mass concentration of toluene in the gas phase is 97 mg/L.Determine the
Henry’s Law constant in units of M/atm.
