Oxygen, nitrogen, and argon gases are mixed in a sealed chamber. The pressure inside the chamber is 150.0 kPa. If the partial pressure of oxygen is 43.5 kPa and the partial pressure of nitrogen is 79.5 kPa, what is the partial pressure of argon?

Answer:

P(Ar) = 27 Kpa

Explanation:

Given data:

Total pressure of tire = 150.0 Kpa

Partial pressure of Oā‚‚ = 43.5 Kpa

Partial pressure of Ar Ā = ?

Partial pressure of Nā‚‚ = 79.5 kPA

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) = Pā‚ + Pā‚‚ + Pā‚ƒ+ ............+Pā‚™

Now we will solve this Ā problem by using this law.

P(total) = POā‚‚ + Ā PNā‚‚ + P(Ar)

150.0 Kpa = 43.5 Kpa + 79.5 Kpa + P(Ar)

150.0 Kpa = 123 Kpa + P(Ar)

P(Ar) = 150.0 Kpa - 123 Kpa

P(Ar) = 27 Kpa
