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

Quizplus · Accepted Answer

To find the total pressure of the system, we need to use Dalton's Law of Partial Pressures which states that the total pressure of a mixture of gases is the sum of the partial pressures of the individual gases in the mixture.

Partial pressure of nitrogen = 0.78 x 11.1 atm = 8.658 atm
Partial pressure of carbon dioxide = 0.22 x 11.1 atm = 2.442 atm

Total pressure = 8.658 atm + 2.442 atm = 11.1 atm

Therefore, the total pressure of the system is 11.1 atm, which is closest to option D) 1.75 atm. The other options are not even in the same order of magnitude as the calculated answer.
