Answer:
Partial pressure O₂ = 2.284 atm
Explanation:
This is problem with unit conversion. Let's convert everything to atm
760 mmHg ___ 1 atm
540 mmHg ___ (540 / 760) = 0.710 atm
101325 Pa ____ 1 atm
203303 Pa ____ (203303 / 101325) = 2.006 atm
Total pressure of the mixture = Sum of partial pressure of each gas
0.710 atm (He) + 2.006 (N₂) + Partial Pressure O₂ = 5 atm
Partial pressure O₂ = 5 atm - 2.006 atm - 0.710 atm = 2.284 atm
