Question

Air is a mixture of gasses. By percentage, it is roughly 78 percent nitrogen, 21 percent oxygen, and 1 percent argon. what is the partial pressure of each gas in the container?

Answer 1

pN2 = 592.8mmHg

pO2 = 159.8mmHg

pAr = 7.6mmHg

Explanations:

Partial pressure is the pressure that would be exerted by one the gases in a mixture.

Using the atmospheric pressure of 760mmHg

For Nitrogen

Partial pressure of Nitrogen = 78% of atmospheric pressure

Partial pressure of Nitrogen = 0.78 * 760mmHg

Partial pressure of Nitrogen = 592.8mmHg

For Oxygen

Partial pressure of oxygen = 21% * 760

Partial pressure of oxygen = 0.21 * 760

Partial pressure of oxygen = 159.6mmHg

For Argon

Partial pressure of Argon = 1% * 760

Partial pressure of Argon = 0.01 * 760

Partial pressure of Argon = 7.6mmHg
