How do you Convert pounds of chlorine to gallon?

Answer 1

You need to know the density of the chlorine which is affected by the temperature and pressure at which the chlorine is.

Once you know the density, you can convert it using:

density = mass/volume

→ volume = mass/density.

You'll need to know the density in pounds per gallon.

Answer 2

You cannot because the answer depends on the pressure under which the chlorine is stored.
