Question

determine the total pressure of a gas mixture that contains O2, N2 and He, if the partial pressure of the gases are : P(O2) = 200 mm Hg, P (N2) = 350 mm Hg, P ( He2) = 428 mm Hg
​

Answer 1

Answer:

P(total) = 978 mmHg

Explanation:

Given data:

Total pressure of gas = ?

Partial pressure of O₂ gas = 200 mmHg

Partial pressure of N₂ gas = 350 mmHg

Partial pressure of He gas = 428 mmHg

Solution:

According to Dalton law of partial pressure,

The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.

Mathematical expression:

P(total) = P₁ + P₂ + P₃+ ............+Pₙ

P(total) = P(O₂) + P(N₂) + P(He)

P(total) = 200 mmHg + 350 mmHg + 428 mmHg

P(total) = 978 mmHg

Answer 2

The total pressure of a gas mixture that contains oxygen, nitrogen and helium gas is 978mmHg.

What is Dalton's Law?

According to the Dalton's law of gas, the total pressure of the gas present in any container is equal to the sum of the partial pressure of the individual gases present in that container.

Given that,

Partial pressure of Nitrogen gas = 350mmHg

Partial pressure of Oxygen gas = 200mmHg

Partial pressure of Helium gas = 428mmHg

Total pressure of mixture = 350 + 200 + 428 = 978mmHg

Hence, total pressure of the mixture is 978mmHg.
