Question

Quizplus · Accepted Answer

The mole fraction of a gas is the ratio of the partial pressure of that gas to the total pressure of the mixture. In this case, the partial pressure of He is 0.60 atm and the total pressure is 0.60 atm + 0.80 atm = 1.40 atm. Therefore, the mole fraction of He is 0.60 atm / 1.40 atm = 0.43.

The Mole Fraction of He Is 0
