Question

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?

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

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.

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.

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.

None of these statements are true.

Explanation / Answer

From the ideal gas equation:

PV = nRT

For the two containers filled with gas have same pressure, Volume , Temperature then the from the ideal gas equation, they must have the same the number of moles

Option b is the right answer.
