I have to make a solution of 10,000ppm hypochlorite, since 1ppm is like 1mg/l for a solute in water solution. Does this mean that i have to add 10,000mg hypochlorite in 1liter water? If hypochlorite is in a liquid form, should i take into account its density and from that to find the volume i add to the water to get a total of 1 litre? Besides; Is 1ppm the same like 1mg/l ? Or does it depend in other factors like both the densities of the solute and solvent? Hope for ideas. THanks.
