Question:

The American Dental Association recommends that an adult female should consume 3.0mg of fluoride (F-) per day to prevent tooth decay.

If the fluoride is consumed as sodium fluoride (45.24% F), what amount of sodium fluoride contains the recommended amount of fluoride?

Answer in mg's.

6.6mg

Why did the tooth go to the circus?

Because it wanted to get some fresh fluoride!

Now, let's calculate the amount of sodium fluoride needed to meet the recommended fluoride intake.

If an adult female needs to consume 3.0mg of fluoride, and sodium fluoride contains 45.24% fluoride, we can set up a simple equation:

0.4524 * x = 3.0

(Sodium fluoride concentration) * (Amount of sodium fluoride) = Recommended amount of fluoride

Solving for x, we find:

x = 3.0 / 0.4524

x ≈ 6.63 mg

So, you would need approximately 6.63 mg of sodium fluoride to meet the recommended fluoride intake! Keep those pearly whites shining!

To find the amount of sodium fluoride that contains the recommended amount of fluoride, we need to first calculate the actual amount of fluoride required.

Given that an adult female should consume 3.0mg of fluoride per day, and sodium fluoride (NaF) is 45.24% fluoride, we can express this as a mathematical equation:

Amount of sodium fluoride = Amount of fluoride required / Percentage of fluoride in sodium fluoride

In this case, the amount of fluoride required is 3.0mg and the percentage of fluoride in sodium fluoride is 45.24%.

Using the equation:

Amount of sodium fluoride = 3.0mg / 0.4524

Now, let's calculate the amount of sodium fluoride:

Amount of sodium fluoride = 6.631mg

Therefore, the recommended amount of fluoride can be obtained by consuming approximately 6.631mg of sodium fluoride.
