Parts per million (ppm), is a ratio of parts of solute to one million parts of solution, and is usually applied to very dilute solutions. It is often found in reports of concentration of water contaminants. To calculate parts per million, divide the mass of the solute by the total mass of the solution.

The concentration of a solution may be expressed as molarity (M), percent by volume, percent by mass, or parts per million (ppm). (3.1pp) The addition of a nonvolatile solute to a solvent causes the boiling point of the solvent to increase and the freezing point of the solvent to decrease.

Students know how to calculate the concentration of a solute in terms of grams per liter, molarity, parts per million, and percent composition. Students know the relationship between the molality of a solute in a solution and the solution's depressed freezing point or elevated boiling point. Chemical Thermodynamics

The "technical" definition of parts per million is: Since the amount of solute relative to the amount of solvent is typically very small, the density of the solution is to a first approximation the same as the density of the solvent. For this reason, parts per million may also be expressed in the following two ways: Parts per billion (ppb):

parts per million/billion/trillion (ppm/ppb/ppt) ppm = (mass fraction) x 106. ppb = (mass fraction) x 109. ppt = (mass fraction) x 1012. Used for very dilute solutions (for example pollutants in drinking water). Notice that mass percent could also be called parts per hundred. 25 grams of a chemical is dissolved in 75 grams of water.
