kPa, respectively?

Answer:

P(O₂) = 26KPa

Explanation:

Given data:

Total pressure = 150 KPa

Partial pressure of nitrogen = 100 KPa

Partial pressure of carbon dioxide = 24 KPa

Partial pressure of oxygen = ?

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

Now we will solve this  problem by using this law.

P (total) = P(O₂) + P(N₂) + P(CO₂)

150 KPa =   P(O₂) + 100 KPa + 24 KPa

150 KPa = P(O₂) + 124 KPa

P(O₂) = 150 KPa  - 124 KPa

P(O₂) = 26KPa
