contain 8.3 ppm of radon. What is the partial pressure of radon

in the basement if the total pressure is 755 torr?

**DrBob222**, Monday, November 7, 2011 at 9:55pmI assume that is 8.3 ppm v/v; if so I would convert that to percent.

(8.3E-6 L/10^6 L)* 100 = mole percent = about 8.3E-10%. Convert that to a fraction (divide by 100) to give mole fraction Rn_, then

p_{Rn}= X_{Rn}P_{total}

**DrBob222**, Tuesday, November 8, 2011 at 11:42amI erred here. 8.3 ppm should be expressed as 8.3E-6 mole fraction Rn.
