Chapter 23, Problem 23.7P

Interpretation Introduction

Interpretation:

Weight percent of $\text{1, 2-ethanediol}$ in original sample has to be calculated.

Concept Introduction:

The relation between the absorbance and concentration of the analyte is calculated from the Lambert Beer’s law as follows:

    $\text{A}=\left(\text{ε}\right)\left(\text{c}\right)\left(\text{l}\right)$

Here, $\text{A}$ is absorbance.

$\text{ε}$ is molar absorption coefficient.

$\text{c}$ is concentration of analyte.

$\text{l}$ is optical path length.
