A scientist is examining a mixture of nitrogen, hydrogen, and ammonia. The individual pressures that are exerted by nitrogen
and hydrogen are 0.26 atm and 0.28 atm, respectively. If the total pressure is 0.90 atm, what is the partial pressure of
ammonia?
Use Pr=P1+P2+P3+...+Pn.

Considering the Dalton's partial pressure, the partial pressure of ammonia is 0.36 atm.

Dalton's law

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= P₁ + P₂ + ... + Pn

where n is the amount of gases in the gas mixture.

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

Partial pressure of ammonia

In this case, you know:

  • PT= 0.90 atm
  • Pnitrogen= 0.26 atm
  • Phydrogen= 0.28 atm
  • Pammonia= ?

Considering the Dalton's law:

PT= Pnitrogen + Phydrogen + Pammonia

you get:

0.90 atm= 0.26 atm + 0.28 atm + Pammonia

Solving:

0.90 atm - 0.26 atm - 0.28 atm= Pammonia

0.36 atm= Pammonia

Finally, the partial pressure of ammonia is 0.36 atm.
