The total pressure exerted by a mixture of O₂, N₂ and He gases is 3.50 atm. What is the partial pressure in atmospheres of the O₂, given that the partial pressure of N₂ is 1.75 and the partial pressure of He is 0.85 atm?

Question

Quizplus · Accepted Answer

The total pressure is the sum of the partial pressures of all gases in the mixture. To find the partial pressure of $O_2$, subtract the given partial pressures of $N_2$ and He from the total pressure: $3.50 - 1.75 - 0.85 = 0.90$ atm.
