To aid in the prevention of tooth decay, it is recommend that drinking water contain 0.700 ppm fluoride (F-).

(a) How many grams of F- must be added to a cylindrical water reservior having a diameter of 4.23 x 102 m and a depth of 18.92 m?

(b) How many grams of sodium fluoride contain this much fluoride?

Thanks for the help!

In the article Tooth Decay: A Delicate Balance, we learn that tooth decay occurs when the equilibrium between mineralization and demineralization becomes unsteady, according to this equation: Ca5(PO4)3(OH) ↔ 5 Ca2+ + 3 PO43- + OH- When a tooth decays, which way do we expect the equilibrium to lie? What does that tell us about the magnitude of K for this reaction?

It is recommended that drinking water contain 1.6 ppm of fluoride. If the local reservoir has a diameter of 450.0 m and a depth of 10.0 m (V= Pi*r2 *h), how many grams of F should be added to the water in the reservoir to give the recommended concentration? If fluoride is provided by hydrogen hexafluorosilicate (H2SiF6), how many grams of H2SiF6 contain Fluoride?

The Environmental Protection Agency has determined that safe drinking water should, on average, contain no more than 1.3 mg/liter of copper. You are testing water from a new source, and take 31 water samples. The mean copper content in your samples is 1.46 mg/l and the standard deviation is 0.18 mg/l. (a) Is there convincing evidence at the α = 0.05 significance level that the water from this source contains unsafe levels of copper? (Do a 4-step process) (b) Referring...
