In water solution, the concentration C in parts-per million (ppm) is equal to the concentration C in milligrams per kilogram (mg/kg) and equal to 1000000 times the molar concentration (molarity) c in moles per liter (mol/L), times the solute molar mass in grams per mole (g/mol), divided by the water solution density at temperature of 20ºC 998 molality = molessolute kilogramssolvent Mathematical manipulation of molality is the same as with molarity. Another way to specify an amount is percentage composition by mass (or mass percentage, % m/m).
