The mole fraction of helium in a vessel that contain threes gases with a partial pressure of : 100 torr oxygen, 300 torr helium and 200 torr neon is 0.50

calculation

mole fraction = partial pressure for helium divided by total pressure
Total pressure=partial pressure of oxygen + partial pressure for Helium +partial pressure for neon

= 100+300+200=600

mole fraction is therefore= 300/600= 0.50
