Answer:
0.70 atm - Option C
Explanation:
Let's apply the mole fraction concept to solve this:
Partial pressure of a gas / Total pressure = Mole fraction of a gas.
In a mixture, sum of mole fraction from each gas = 1
Partial pressure of Oâ‚‚ / Total pressure = Mole fraction of Oâ‚‚
0.43 atm / 1.13 atm = 0.380
1 - 0.380 = 0.62 → Mole fraction N₂
Mole fraction Nâ‚‚ = Partial pressure Nâ‚‚ / Total pressure
0.62 = Partial Pressure Nâ‚‚ / 1.13 atm
0.62 . 1.13 = 0.70 atm → Partial Pressure N₂
