The correct answer is:
The container holding the gases must be at standard temperature and pressure.
The conversion factor of 22.7 L/mol is applicable under standard temperature and pressure (STP) conditions, which are defined as 0 degrees Celsius (273.15 K) and 1 atmosphere of pressure. This is true for any ideal gas regardless of its composition.
