A gas cylinder at a pressure of 4408 torr contains a mixture of N₂, O₂, and helium gases. If the partial pressure of N₂ gas is 1520 torr and the partial pressure of helium is 25 torr, what is the partial pressure of O₂?

Question

Quizplus · Accepted Answer

The total pressure in the gas cylinder is the sum of the partial pressures of all the gases present. To find the partial pressure of O₂, subtract the partial pressures of N₂ and helium from the total pressure: 4408 torr - 1520 torr - 25 torr = 2863 torr.
