The total pressure exerted by a mixture of O₂, N₂ and He gases equals 10.0 atm. What is the partial pressure of O₂ if the partial pressure of N₂ is 5.0 atm and the partial pressure of He is 3.0 atm?

Question

Quizplus · Accepted Answer

The total pressure of a gas mixture is the sum of the partial pressures of the individual gases. Given the total pressure is 10.0 atm, and the partial pressures of N2 and He are 5.0 atm and 3.0 atm respectively, the partial pressure of O2 can be found by subtracting these from the total pressure: 10.0 atm - 5.0 atm - 3.0 atm = 2.0 atm.
