Answer to Question #251494 in General Chemistry for lala

Question

You are task to collect gases such as N2, O2, CO2, AND Ar gas. The partial pressure of the gases are 515 torr, 215 torr, and 98 torr respectively. What is the partial pressure of Ar, if the total pressure is 715 torr.

Answer 1

In a mixture of gases each gas exerts the same pressure that it would if it alone occupied the container. In a mixture of gases the pressure each gas exerts is called its partial pressure, and the total pressure of the mixture is the sum of the partial pressures of the constituent gases.
