Mole fraction of O2 = 571 Correct The mole fraction is the ratio of the number of moles of a given component in a mixture to the total number of moles in the mixture. The mole fractions can be represented in terms of pressures The total pressure PTOTAL = 0.180 atm +0.240 atm = 0.420 atm The mole fraction of CH4 in the mixture PCH 0.180 atm 0.420 atm = 0.429 PTOTAL Since it is the mixture of two gases,...
