Answer:
Partial pressure O₂ = 1.49 atm
Explanation:
We can solve this, by the mole fraction concept.
Mole fraction = Moles of gas / Total moles
We can also define mole fraction as: Partial pressure of a gas / Total pressure
Total moles = Moles of O₂ + Moles of N₂
36.5 g. 1 mol / 32g + 46.4 g . 1mol /28g = 2.79 moles
1.14 moles O₂ + 1.65 moles N₂ = 2.79 moles
Partial pressure O₂ / Total pressure = Moles of O₂ / Total moles
Partial pressure O₂ = (Moles of O₂ / Total moles) . Total pressure.
We replace: (1.14 mol / 2.79 mol) . 3.64 atm = 1.49 atm
Partial pressure O₂ = 1.49 atm
