A sample consisting of various gases contains 2.6 106 mole fraction of radon. This gas at a total pressure of 37 atm is shaken with water at 30°C. Calculate the molar concentration of radon in the water.
Can somepne please provide a step by step instruction?

partial pressure = k*c
with c in moles/L.
You don't provide a k and I don't know it by memory; however, look up k (k is available in many different unitsfor this formula you want k in units of atm*L/mol which is the same as atm/M). To obtain partial pressure of the Rn it is mole fraction Rn*total P.
