Henry's law may be expressed in different ways and with different concentration units, resulting in different values for the Henry's law constants. If mole fraction is used as the concentration unit, one algebraic statement of the law is: Pgas = kHXgas where k is the Henry's law constant in units of pressure, usually atm. At 25°C, some water is added to a sample of gaseous oxygen (O2) at 3.54 atm pressure in a closed vessel and the vessel is shaken until as much oxygen as possible dissolves. Then 7.88 kg of the solution is removed and boiled to expel the oxygen, yielding a volume of 0.936 L of O2(g) at 0°C and 1.00 atm. Determine the Henry’s law constant for oxygen in water based on this experiment.
