Agas mixture contains .150 mol of o2 and .211 mol of ar gas. what is the mole fraction of o2 in the mixture

0.4155 is the mole fraction of oxygen gas in the mixture.

Explanation:

Mole fraction is defined as ratio of moles of specific to the total moles of all the compounds present in the mixture.

Moles of oxygen gas =

Moles of argon gas =

Mole fraction of oxygen gas =

=

Mole fraction of argon gas =

=

0.4155 is the mole fraction of oxygen gas in the mixture.

0.5845 is the mole fraction of argon gas in the mixture.
