Chapter 9.6, Problem 9.11P

Interpretation Introduction

Interpretation:

Concentration in $\text{ppm}$ and amount allowed in $\text{100g}$ of water is to be identified.

Concept Introduction:

In order to express the concentration, many units have been used. One among them is parts per million $(ppm)$ defines as one milligram of solute per liter of solution or one milligram of solute per kilogram of solution.

Expressed as,

$\text{1}\text{ppm}\text{=}\frac{\text{1}\text{mg}\text{solute}}{\text{1}\text{L}\text{solution}}\text{=}\frac{\text{1}\text{mg}\text{solute}}{\text{1}\text{kg}\text{solution}}$
