Question

6. A mixture of gases contains 2 mole of N2, 4 mole of H2, and 4 mole of NH3. If the total pressure of the mixture is 20 atm, what is the partial pressure of Nz?* (3 Points) 3 atm 1 4 atm 5 atm 2 atm

Answer 1

Answer:To determine the partial pressure of N2 in the mixture of gases, we need to use the mole ratios of the gases.

Given:

- 2 moles of N2

- 4 moles of H2

- 4 moles of NH3

To find the partial pressure of N2, we can use Dalton's law of partial pressures, which states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of each gas component.

First, let's find the mole fraction of N2 in the mixture:

Mole fraction of N2 = moles of N2 / total moles of all gases

Mole fraction of N2 = 2 / (2 + 4 + 4) = 2/10 = 0.2

Now, we can calculate the partial pressure of N2:

Partial pressure of N2 = mole fraction of N2 * total pressure

Partial pressure of N2 = 0.2 * 20 atm = 4 atm

Therefore, the partial pressure of N2 in the mixture is 4 atm.
