According to the Avogadro's law, different gases have an equal volume at room temperature (25˚C) and 1 atm.
1 mole of a gas = 24 dm^3 (cubic decimeter)
For your information, 1 cubic decimeter = 1000 cubic meter.
For example, if you have 2 moles of oxygen gas, the volume of it would simply be 2*24dm^3 = 48dm^3. You can just multiply 24dm^3 by the number of moles to obtain the volume of gas.
