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 O₂ / Total pressure = Mole fraction of O₂

0.43 atm / 1.13 atm = 0.380

1 - 0.380 = 0.62 → Mole fraction N₂

Mole fraction N₂ = Partial pressure N₂ / Total pressure

0.62 = Partial Pressure N₂ / 1.13 atm

0.62 . 1.13 = 0.70 atm → Partial Pressure N₂
