The maximum detected concentration of trihalomethanes (THMs) in a water system was 62.9 microgram/L, which is below the max. permitted level. THMs are compunds with the formula CHXYZ, where X,Y,Z are various combinations of Cl and Br, and are produced by the disinfection of water. An example is chloroform, CHCl3. If chloroform were present at 62.9 microgram/L, and you drank 8 fl. ounces, how many molecules of chloroform would you ingest?
This solution gives calculations and explanations for calculating molecules of chloroform produced by halomethanes in a water system.
