alukav5142 [94]

Answer:

Mole fraction Ar = 0.31

Explanation:

Remember that the sum of the mole fractions in a mixture of gases = 1

Mole fraction = Moles from a gas / Total moles

Mole fraction N₂+ Mole fraction O₂+ Mole fraction SO₂+ Mole fraction CO₂ + Mole fraction Ar = 1

N₂ = 0.21

O₂= 0.16

CO₂ = 0.23

SO₂ = 0.09

Mole fraction Ar = 1 - 0.21 - 0.16 - 0.23 - 0.09

Mole fraction Ar = 0.31
