The total pressure exerted by a mixture of O₂, N₂ and He gases is 1.50 atm. What is the partial pressure in atmospheres of the O₂, given that the partial pressure of N₂ is 0.75 atm and the partial pressure of He is 0.33 atm?

Question

Quizplus · Accepted Answer

The partial pressures of all components in the mixture sum to the total pressure: P(total) = P(O₂) + P(N₂) + P(He) Substituting the given values: 1.50 atm = P(O₂) + 0.75 atm + 0.33 atm Solving for P(O₂): P(O₂) = 1.50 atm - 0.75 atm - 0.33 atm = 0.42 atm Therefore, the partial pressure of O₂ is 0.42 atm.
