Let's first assume 200 ppm = 200 mg/L. Then, divide the result by 1000 to get g/L: 200 mg/L divided by 1000 mg/g = 0.2 g/L. Next, divide 0.2 g/L by the molar mass of NaOH to get the molarity: 0.2 g/L divided by 39.997 g/mol = 0.005 mol/L. 2. Calculate the dilution recipe 1 ppm = 0.001 ml/l and hence 1 ml/l = 1000 ppm. Use this online unit conversion calculator to convert Parts Per Million to Milliliter Per Liter.
