Answer to Question #138460 in General Chemistry for Javier

Question

A gas mixture containing oxygen, nitrogen, and helium exerts a total pressure of 925 torr .

If the partial pressures are oxygen 445 torr and helium 50 torr, what is the partial pressure (torr) of the nitrogen in the mixture?

Answer 1

Solution:

Mixture of gas = N₂ + O₂ + He

Given:

Pressure_(total) = 925 torr

Pressure_(oxygen) = 445 torr

Pressure_(helium) = 50 torr

Pressure_(nitrogen) = ?

925 - 445 - 50 = 430 torr

Answer:

Partial pressure of nitrogen gas is 430 torr.
