(Answer) The mole fraction of oxygen in the mixture is 0.415.
Mole fraction of a gas in a mixture of gases is the ratio of the moles of the gas to the sum of moles of all gases in the mixture.
Moles of oxygen gas in the mixture = 0.150
Moles of argon gas in the mixture = 0.211
Total moles of gases in the mixture = (0.150 + 0.211) = 0.361
Mole fraction of oxygen gas = [tex]\frac{0.150}{0.361} = 0.415[/tex]
Answer:
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.
[tex]\chi_i=\frac{n_i}{n_1+n_2+..n_i}[/tex]
Moles of oxygen gas = [tex]n_1=0.150 mol[/tex]
Moles of argon gas = [tex]n_2=0.211 mol[/tex]
Mole fraction of oxygen gas =
= [tex]\chi_1=\frac{n_1 }{n_1+n_2}=\frac{0.150 mol}{0.150 mol+ 0.211 mol}=0.4155[/tex]
Mole fraction of argon gas =
= [tex]\chi_2=\frac{n_2 }{n_1+n_2}=\frac{0.211 mol}{0.150 mol+ 0.211 mol}=0.5845[/tex]
0.4155 is the mole fraction of oxygen gas in the mixture.
0.5845 is the mole fraction of argon gas in the mixture.
