Air is made of nitrogen, carbon dioxide, and small amounts of other gases. What is the pressure of O₂, total is 1 atm if PN₂ = 5
Stolb23 [73]

Answer:

The pressure of O₂ is 0.8 atm.

Explanation:

The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

PT = PA + PB

This relationship is due to the assumption that there are no attractive forces between the gases.

In this case:

PT=Pnitrogen + Pcarbon dioxide + Pother gases

Being:

  • Pnitrogen: 593.4 mmHg
  • Pcarbon dioxide: 3 mmHg
  • Pother gases: 7.1 mmHg

and replacing:

PT= 593.4 mmHg + 3 mmHg + 7.1 mmHg

you get:

PT= 603.5 mmHg

Being 760 mmHg= 1 atm, you get:

PT= 603.5 mmHg= 0.8 atm

<u><em>The pressure of O₂ is 0.8 atm.</em></u>
