Unformatted text preview: XP T = P P Mole fraction(X) = moles of substance/total moles. To figure out the mole fraction, we need to figure out the number of moles of each gas. This is a simple conversion of grams to moles as shown below: 2g He1mol He = 0.5 mol He 4g He 10g Ne1mol Ne = 0.5mol Ne 20g Ne 40g Ar1mol Ar = 1mol Ar 40 g Ar There are 2 total moles of gas which means that the mole fraction of He = 0.25, the mole fraction of Ne = 0.25, and the mole fraction of Ar = 0.5. Using XP T = P P : P P He: (0.25)(600torr) = 150torr P P Ne: (0.25)(600torr) = 150torr P P Ar: (0.50)(600torr) = 300torr...
