You have two separate containers each filled with a gas. The containers have the same volume and are at the same temperature. The gases also exert the same pressure. Which of the following statements are true?

a. For conditions of P, V, and T to be the same, the gases must be identical.

b. For conditions of P, V, and T to be the same, the gases can be different but the number of moles of gas in each balloon must be the same.

c. For conditions of P, V, and T to be the same, the gases can be different but the mass of gas in each balloon must be the same.

d. For conditions of P, V, and T to be the same, the gases can be different but the molar mass of gas in each balloon must be the same.

e. None of these statements are true.

The best option is:

b. For conditions of P, V, and T to be the same, the gases can be different but the number of moles of gas in each balloon must be the same.

Explanation:

This is in accordance with Avogadro's law which states that equal volume of all gase under the same temperature and pressure contains the same number of mole.

From this law, V varies as T and P as in the option. So For conditions of P, V, and T to be the same, the gases can be different but the number of moles of gas in each container must be the same.
