Chapter 12, Problem 46E

Interpretation Introduction

Interpretation:

The mass of sodium (in mg) consumed is to be calculated.

Concept Introduction:

Solutions are homogeneous mixtures made up of two components, the solute and the solvent.

The same solutes and solvents can form a number of combinations by varying their amounts. These combinations can be differentiated in terms of concentration of solutions. Concentration of a solution is defined as the amount of solute present in the given amount of solvent.

There are many ways of expressing concentration of a solution, such as mass percent, volume percent, molarity, parts per million.

Mass percent is defined as the mass of solute present in $100$ g of a solution.

Volume percent is defined as the mass of solute present in $100$ mL of a solution.

Parts per million is defined as the mass of solute present in ${10}^6$ g of a solution. It is used for expressing concentration when a small amount of solute is present in the solution.

$\text{Density = }\frac{\text{Mass of water (g)}}{\text{Volume of water (L)}}$

It is known $\text{1 g = 1000 mg}$, conversion factor is as $\frac{\text{1000 mg}}{\text{1 g}}$
