ppm = 1 mg solute per 1 kg solution Then, for an aqueous solution: ppm = 1 mg solute per liter of solution This last one works because the solution concentration is so low that we can assume the solution density to be 1.00 g/mL. Also, it's this last modification of ppm (the mg/L one) that allows us to go to molarity (which has units of mol/L).
