Chapter 8: Q. 8.56 (page 278)

In a gas mixture, the partial pressure are argon 415mmHg, neon 75mmHg, and nitrogen 125mmHg. What is the total pressure, in mmHg, exerted by the gas mixture?

Short Answer

Expert verified

The total pressure is615mmHg.

Step by step solution

01

Given Information

We need to find the total pressure.

02

Simplify

In a gas, mixture, each gas exerts its partial pressure, which is the pressure it would exert if it were the gas in the container. Dalton's law that the total pressure of a gas mixture is the sum of the partial pressures of the gases in the mixture.

The total pressure is:

Argon is PAr=415mmHg

Neon is Pne=75mmHg

Nitrogen is Pn=125mmHg

Ptotal=PAr+Pne+Pn=415mmHg+75mmHg+125mmHg=615mmHg
