Chapter 4, Problem 4.24QP

Interpretation Introduction

Interpretation: The pesticide concentrations are given in milligrams per liter. The concentration of the pesticides in $\text{ppb}$ and millimoles per liter is to be calculated.

Concept introduction: One $\text{ppb}$ is equal to micrograms of the solute present in one liter of the solution.

The concentration of the solution in $\text{ppb}$ of the solution is calculated by the formula,

$\text{Concentration}=\frac{\text{Milligrams}\text{per}\text{liter}}{\text{1000}}$

The concentration in DDT in millimoles per liter of the solution is calculated by the formula,

$\text{Concentration}=\frac{\text{Milligrams}\text{per}\text{liter}}{\text{Molar}\text{mass}}$

To determine: The concentration of pesticide in $\text{ppb}$ and millimoles per liter.
