Chapter 6, Problem 86P

Interpretation Introduction

Interpretation:

The mass of lead in the sample should be calculated.

Concept Introduction:

Parts per million are a convenient concentration unit to use to refer small amount of solute in solution. The molar concentration can be related to the solute-solvent amount in ppm. It is mathematically represented as follows:

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

Here, ppm stands for part per million.
