Question

What is the volume of 3.2 moles of chlorine gas (Cl2) at standard temperature and pressure (STP)?

7.0 L

14 L

22. L

72 L

Answer 1

We are assuming that the gas is ideal. Then, PV = nRT (the Ideal Gas Law) holds. Remember, from the Ideal Gas Law, that 1 mol of a gas at STP is 22.4 L of that gas, regardless of what gas it is. You can prove this using PV = nRT. Since we have 3.2 mol here, the answer is:

(22.4 * 3.2) L, which is approximately 72 L.
