Your pool maintenance guide specifies that the chlorine, Cl₂, 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 3.92 × 10-5 M.
