The U.S. Food and Drug Administration recommends that you consume less than 2.4 g of sodium per day. How much sodium chloride can you consume and still be within the FDA limit?

Interpretation Introduction

Interpretation:

The amount of sodium chloride, which needs to be consumed per day, 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 U.S. Food and Drug Administration recommends that the consumption of sodium per day should be less than 2.4g.

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

1mol Na22.99g Na

And,

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

1mol NaCl58.5g NaCl

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