Question

A gas mixture is composed of three different gases. The first gas in the mixture has a pressure of 0.35 atm. The second gas in the mixture has a pressure of 0.20 atm. The third gas in the mixture has a pressure of 0.65 atm. What is the total pressure of the gas mixture?

Answer 1

The total pressure of the gas mixture is the sum of the partial pressures of its components.

$P = 0,35 atm + 0,20 atm + 0,65atm = 1,20 atm$

The total pressure of the gas mixture is 1,20 atm
