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?
646 mmhg
114 mmhg
160 mmhg
76 mmhg
571 mmhg

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 o Dalton's law of partial pressure:

Partial pressure of oxygen gas :

Partial pressure of carbon dioxide gas :

Partial pressure of nitrogen gas :
