It is recommended that drinking water contain 1.6 ppm fluoride (f-) for prevention of tooth decay. consider a reservoir with a diameter of 4.50 x 102 m and a depth of 10.0 m. (the volume is 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 hexafluorosilicate, h2sif6. how many grams of h2sif6 contain this much f-?
