How much chlorine gas can 1 liter of chlorine yield?

Chlorine gas is a diatomic molecule (Cl₂), and when we refer to its yield from a particular volume, we typically refer to the concept of gas expansion and the ideal gas law. One mole of a gas occupies approximately 22.4 liters at standard temperature and pressure (STP).

In the case of chlorine gas, the molecular weight is around 70.9 grams per mole. If you have 1 liter of liquid chlorine, it can be converted into gas at STP, producing a much larger volume due to the transition from liquid to gas.

When the conversion is calculated, 1 liter of liquid chlorine can yield about 450 liters of chlorine gas. This yield is based on its density and the conditions under which the gas is measured, primarily at STP. Thus, the correct answer reflects the conversion factor from the liquid state to gas under standard conditions, providing a clear indication of how much gas can be derived from that volume of liquid chlorine.

This understanding is crucial in water distribution, where proper dosing and safety measures related to the use of chlorine gas for disinfection can be significantly impacted by the amount of chlorine available for use.
