The scientific consensus indicates that adults should consume about 2.0 mg of fluoride per day for healthy teeth. How much sodium fluoride needs to be consumed to get 2.0 mg of fluoride?

Interpretation Introduction

Interpretation:

The amount of sodium fluoride, which needs to be consumed per day for a healthy tooth, is to be determined.

Concept Introduction:

The characteristic mass of a compound is considered as the formula mass of the compound, which is obtained by adding the atomic masses of all the atoms.

A conversion factor is considered a numerical ratio in order to change one unit into another.

A chemical formula represents the precise number of atoms in a molecule, but not their structural arrangement.

Explanation of Solution

Given information: The scientific consensus indicates that adults should consume about 2.0mg of sodium fluoride per day.

The equivalence is obtained between grams of fluorine (F) and moles of fluorine (F) with the help of the chemical formula as follows:

1mol F19.00g F

And,

The equivalence is obtained between grams of sodium fluoride (NaF) and moles of sodium fluoride (NaF) with the help of the chemical formula as follows:

1mol NaF41.99g NaF

In order to obtain the amount of sodium fluoride, the conversion factor proceeds as follows:
