![]() ![]() What percentage is 100 ppm?ĥ00 ppm translates to 500 mg/L. One thousanth of a gram is one milligram and 1000 ml is one liter, so that 1 ppm = 1 mg per liter = mg/Liter.ġ000 ppm is a concentration of 1000 mg/L of solution and is equivalent to 1000 ug/ml or 1000 ng/ul or 1 g/L or 0.1 g/100 ml. One gram in 1000 ml is 1000 ppm and one thousandth of a gram (0.001g) in 1000 ml is one ppm. The equation for determining ppm then simplifies to: ppm = (milligrams of solute) / (liters of solution). Thus, the units of grams and milliliters of such solutions become interchangeable. In these cases, the volume of the solution in milliliters is equal to the mass of the solution in grams. Convert the mass in grams to a mass in milligrams: mass NaCl = 0.0045 g = 0.0045 g × 1000 mg/g = 4.5 mg.Extract the data from the question: mass solute (NaCl) = 0.0045 g.Write an equation representing the ppm concentration: ppm = mass solute (mg) ÷ volume solution (L).Parts Per Million (ppm) Concentration Calculations How do you calculate ppm of a solution?. ![]()
