QUESTION:

Nitrogen (\(\mathrm{N}_{2}\)) at 150 kPa, \(40^{\circ} \mathrm{C}\) occupies a closed, rigid container having a volume of 1 m3. If 2 kg of oxygen (\(\mathrm{O}_{2}\)) is added to the container, what is the molar analysis of the resulting mixture? If the temperature remains constant, what is the pressure of the mixture, in kPa?

ANSWER:

Step 1 of 5

Nitrogen  at:

- -Pressure.

- -Temperature.

- -Tank volume.

- -Oxygen mass.

We assume:

- Ideal gas behavior.

- Steady-state flow.

- The change in kinetic and potential energy is neglected.

We need to determine molar fraction and final pressure.
