You can perform the unit conversion the other way, too. Remember, for dilute solutions, you can use the approximation that 1 ppm is 1 mg/L. Use the atomic masses from the periodic table to find the molar mass of the solute. This chemistry video tutorial explains how to convert the solution concentration from parts per million or ppm to Molarity.My Website: https://www.video-tut TDS is expressed in units of mg per unit volume of water (mg/L) or also referred to as parts per million (ppm). Typically, natural mineral water and tap water can have a TDS value of 100-200 mg/l. In areas with high concentration of minerals, the natural tap water could however be considerably higher.
