Question

How the volume of a gas is related to the number of moles? What is the volume of one mole of a gas at STP? [2 marks]

Answer 1

At constant temperature and pressure, the volume of a gas depends on the number of molecules, and not on the size and type of molecules. Therefore, as the number of moles of a gas increases, volume of the gas increases. [1 Mark]
One mole of any gas at STP occupies 22.4 L of volume. [1 Mark]
