Question

Q2. One-third of a gaseous mixture is nitrogen and 2/3 of the
gas is helium. The total pressure in the container is 3
atmospheres. What is the partial pressure of the nitrogen?​

Answer 1

Answer:

The total pressure in the container is 3 atmospheres. ... 5 moles of Nitrogen and 10 moles of Helium are present. ... total pressure exerted by a mixture of non- reacting gases is equal to the sum of the partial pressures

Answer 2

Answer:

The partial pressure of nitrogen in the mixture is 1 atmosphere.

Explanation:

We know that the gaseous mixture is made up of nitrogen and helium. Let's assume that the total volume of the mixture is constant and equal to V.

Since one-third of the mixture is nitrogen, the fraction of the mixture that is nitrogen is 1/3. Similarly, the fraction of the mixture that is helium is 2/3.

Therefore, the partial pressure of nitrogen, P(N2), is equal to:

P(N2) = (1/3) x total pressure

And the partial pressure of helium, P(He), is equal to:

P(He) = (2/3) x total pressure

We are given that the total pressure in the container is 3 atmospheres, so we can substitute this into the equations above to find the partial pressures:

P(N2) = (1/3) x 3 = 1 atmosphere

P(He) = (2/3) x 3 = 2 atmospheres

Therefore, the partial pressure of nitrogen in the mixture is 1 atmosphere.
