# Problem: Decide it is time to clean your pool since summer is quickly approaching. Your pool maintenance guide specifies that the chlorine, CI2, 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 CI2 content. The chemist reports a chlorine concentration of 2.17 times 10 -5 M. Convert the concentration of CI2 to parts- per- million (ppm).
