Question

A storage tank contains n, o, and co2. The partial pressure of n and o gas are 600 torr and 150 torr. The total pressure is 825 torr. What is the partial pressure and mole fraction of co2?

Answer 1

The partial pressure of carbon dioxide is 75 torr.

What is Dalton's theory?

Dalton's theory of gas states that total pressure of the mixture of gas sample is equal to the sum of the partial pressure of all the gases present in that sample.

Given that,

• Total pressure of mixture = 825 torr
• Partial pressure of Nitrogen = 600 torr
• Partial pressure of oxygen = 150 torr
• Partial pressure of carbon dioxide = ?

On putting values, we get

Partial pressure of carbon dioxide = 825 - (600 + 150) = 75 torr

Hence Partial pressure of carbon dioxide is 75 torr.
