AP CHEM! PLEASE HELP

posted by .

A sample consisting of various gases contains 2.6 10-6 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 units--for 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.
