Imagine a planet that has a similar atmospheric pressure to earth (760 mmhg) but different concentrations of gases in its atmosphere. on this hypothetical planet, oxygen makes up 10% of the atmosphere, carbon dioxide makes up 15%, and nitrogen makes up the remaining 75%. based on this information, what is the partial pressure of oxygen on this new planet?

"76 mmHg" is the partial pressure of oxygen on this new planet.

Explanation:

Atmospheric pressure on air on earth = 760 mmHg

On an unknown planet :

Oxygen makes up 10% of the atmosphere.

The mole fraction of oxygen gas can be written as

Carbon dioxide makes up 15% of the atmosphere.

The mole fraction of carbon dioxide gas can be written as

Nitrogen makes up the remaining 75% of the atmosphere.

The mole fraction of nitrogen gas can be written as

Atmospheric pressure of air on unknown planet,p= 760 mmHg (given)

Partial pressure of gases can be calculated by the help of Dalton's law of partial pressure:

Partial pressure of oxygen gas :

Partial pressure of carbon dioxide gas :

Partial pressure of nitrogen gas :

"76 mmHg" is the partial pressure of oxygen on this new planet.
