The centers for disease control and prevention (CDC) develops recommendations for water fluoridation along with technical requirements for each major compound used.
<h3>What is meant by water fluoridation?</h3>
Almost all water contains some fluoride, but usually not enough to prevent tooth decay. Fluoride can also be added to drinking water supplies as a public health measure for reducing cavities. Water fluoridation is the process of adding fluoride to the water supply so the level reaches approximately 0.7 ppm or 0.7 milligrams of fluoride per liter of water, this is the optimal level for preventing tooth decay.

Answer:
0.48 moles
Explanation:
The bromide has a molarity of 2.6M.
This simply means that in 1dm^3 or 1000cm^3 of the solution, there are 2.6 moles.
Now, we need to get the number of moles in 185ml of the bromide. It is important to note that the measurement ml is the same as cm^3.
We calculate the number of moles as follows.
If 2.6mol is present in 1000ml
x mol will be present in 185 ml.
To calculate x = (185 * 2.6) ÷ 1000
= 0.481 moles = 0.48 moles to 2 s.f
