The presence of the radioactive gas radon (Rn) in well water obtained from aquifers that lie in rock deposits presents a possible health hazard in parts of the United States.
(a) Assuming that the solubility of radon in water with 1 atm pressure of the gas over the water at 30°C is 7.27 10-3 M, what is the Henry's law constant for radon in water at this temperature?
(b) A sample consisting of various gases contains 3.4 10-6 mole fraction of radon. This gas at a total pressure of 33 atm is shaken with water at 30°C. Calculate the molar concentration of radon in the water.
