Henry's law may be expressed in different ways and withdifferent concentration units, resulting in different values forthe Henry's law constants. If mole fraction is used as theconcentration 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 gaseousxenon (Xe) at 4.15 atm pressure in a closed vessel and the vesselis shaken until as much xenon as possible dissolves. Then 1.81 kgof the solution is removed and boiled to expel the xenon, yieldinga volume of 0.789 L of Xe(g) at 0°C and 1.00 atm. Determine theHenry’s law constant for xenon in water based on thisexperiment.
