It is recommended that drinking wtaer contain 1.6 ppm fluoride (F-) for prevention of tooth decay. Consider a reservoir with a diameter of 4.50x10^2m and a depth of 10.0m. (The volume is pi x r^2 x h, where r is the radius and h is the height.) How many grams of F- should be added to give 1.6 ppm? Fluoride is provided by hydrogen hexafluosilicate, H_2SiF_6. How many grams of H_2SiF_6 contain this much F-?
