The units of parts per million (ppm) and parts per billion (ppb) are commonly used by environmental chemists. In general, 1 ppm means 1 part of solute for every 10° parts of solution. Mathematically, by mass: ug solute g solution mg solute kg solution ppm = %3D In the case of very dilute aqueous solutions, a concentration of 1.0 ppm is equal to 1.0 µg of solute per 1.0 mL, which equals 1.0 g solution. Parts per billion is defined in a similar fashion. Calculate the molarity of each of the following aqueous solutions. a. 1.4 ppb Hg in H20 M b. 2.4 ppb CH Cl3 in H2O M c. 66.0 ppm As in H20
