mass fraction and mass (or weight) percent (%) mass fraction = mass of component / total mass of soln. mass % = mass fraction x 100. 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).

For percent solutions, you don't need to know the formula weight of the solute. By definition, a percent solution is the number grams of solute per 100 mL solvent. Thus a 1% solution of sucrose in water is made by taking 1 gram of sucrose and dissolving it in 100 mL of water.
