approaching. Your pool maintenance guide specifies that the chlorine, Cl2, the concentration of the pool should be between 1 and 3 ppm. In order to determine if your pool is safe to swim in, you send a sample of pool water to a chemist for analysis of the Cl2 content. The chemist reports a chlorine concentration of 4.08×10−5 M.  Convert the concentration of Cl2 to parts per million (ppm).
