The volume of the solution is 1 kg: Pleading for scientific writing



“The volume of the solution is 1 kg.”

Something is wrong with this statement. Volume can be expressed in liters but not in kilograms. It doesn't help much to say that aqueous solutions have a density of about 1 kg/L and that it doesn't matter much whether you say “l kg” or “1 L.” The fact remains that the statement is wrong. Fortunately, none of us would write a sentence like this for publication. Tropospheric chemists, however, have a similar habit: “The ozone concentration is 40 ppb.”
