The gases in a mixture have the following partial pressures at the same volume and temperature: 1,013,000 Pa nitrogen, 700 mm argon, 1.20 atm of helium, 790 torr oxygen, and 0.50 atm of carbon dioxide.

Rank these gases in order of increasing mole fraction, putting the gas with the smallest mole fraction first.

Smallest mole fraction

Nitrogen
Argon
Helium
Oxygen
Carbon Dioxide

Largest mole fraction

Anyone can guess in the ranking. How did you arrive at this ranking?
Change the units to the same overall unit--it doesn't matter what you pick but I think atm would be the easiest.
Then X = (partial pressure/total pressure)
