Answer :
Final answer:
The mole fraction of CO₂ in the mixture of 17 g of CO₂ and 39.1 g of O₂ is 0.24.
Explanation:
To find the mole fraction of CO₂ in the mixture, we first need to calculate the number of moles of CO₂ and O₂. The molar mass of CO₂ is 44 g/mol, so 17 g of CO₂ is equal to 17/44 = 0.386 moles. The molar mass of O₂ is 32 g/mol, so 39.1 g of O₂ is equal to 39.1/32 = 1.22 moles. The mole fraction of CO₂ can be calculated by dividing the moles of CO₂ by the total moles of both gases:
Mole fraction of CO₂ = (0.386 moles of CO₂) / (0.386 moles of CO₂ + 1.22 moles of O₂) = 0.24
