If a mixture of gases contained 78% nitrogen at a pressure of 984 torr and 22% carbon dioxide at 345 torr,what is the total pressure of the system?

Question

Quizplus · Accepted Answer

The total pressure of the system is the sum of the partial pressures of the individual gases. The partial pressure of nitrogen is 78% of 984 torr, which is 768 torr. The partial pressure of carbon dioxide is 22% of 345 torr, which is 76 torr. The total pressure of the system is therefore 768 torr + 76 torr = 844 torr.
