A mixture of He, Ne, and N2 gases has a pressure of 1.943 atm. If the pressures of He and Ne are 0.137 atm and 0.566 atm, respec
Ad libitum [116K]

Answer:

The parcial pressure of N₂ in the mixture is 1.24 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=PHe + PNe + PN₂

You know:

  • PT= 1.943 atm
  • PHe= 0.137 atm
  • PNe= 0.566 atm
  • PN₂= ?

Replacing:

1.943 atm= 0.137 atm + 0.566 atm + PN₂

Solving:

1.943 atm= 0.703 atm + PN₂

1.943 atm - 0.703 atm= PN₂

1.24 atm= PN₂

<u><em>The parcial pressure of N₂ in the mixture is 1.24 atm.</em></u>
