A tank containing oxygen, carbon dioxide, and nitrogen gases has a total pressure of 6.7
atm. If the O2 has a pressure of 3.0 atm and the carbon dioxide has a pressure of 1.2
what is the partial pressure of the nitrogen gas?

Answer:

P(Nā‚‚) = 2.5 atm

Explanation:

Given data:

Total pressure of gasses = 6.7 atm

Partial pressure of Oā‚‚ = 3.0 atm

Partial pressure of COā‚‚ = 1.2 atm

Partial pressure of Nā‚‚ = ?

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) = P(Oā‚‚) Ā + P(COā‚‚) + P(Nā‚‚)

6.7 atm = 3.0 atm + 1.2 atm + P(Nā‚‚)

6.7 atm = 4.2 atm + P(Nā‚‚)

P(Nā‚‚) = 6.7 atm - 4.2 atm

P(Nā‚‚) = 2.5 atm
