Chapter 6, Problem 37P

Interpretation Introduction

(a)

Interpretation:

The concentration of species in ppm should be calculated.

Concept Introduction:

Concentration typically relates an amount of solute and the volume of solution. When relating small amounts, we typically use the unit ppm, which measures the number of units of solute per million units of solution. The best way to perform this calculation is to change solute amounts to milligrams and solution amount to kilograms.

This is best described as follows:

$\text{ppm=}\frac{\text{mg}\text{solute}}{\text{kg}\text{solution}}$
