(Solution Download) The presence of the radioactive gas radon Rn in well


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 oC is 7.27 × 10-3, what is the Henry's law constant for radon in water at this temperature?
(b) A sample consisting of various gases contains 3.5 × 10-6 mole fraction of radon. This gas at a total pressure of 32 atm is shaken with water at 30 oC. Calculate the molar concentration of radon in the water?
