Answer:
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:
