Chapter 18, Problem 18.12P

Interpretation Introduction

Interpretation:

The value of molar absorptivity for the given solution has to be calculated at $\text{266}\text{nm}\text{.}$

Concept introduction:

Beer-lambert law:

$\begin{array}{l}\text{A}\text{=}\text{-}\text{log}\frac{\text{P}}{{\text{P}}_{\text{o}}}\text{=}\text{εcb}\\ \text{where,}\\ \text{A}\text{-}\text{absorbance}\\ {\text{P}}_{\text{o}}\text{-}\text{incident}\text{irradiance}\text{and}\text{P}\text{-}\text{transmitted}\text{irradiance}\\ \text{ε}\text{-}\text{molar}\text{absorptivity}\\ \text{c-}\text{concentration}\text{and}\text{b}\text{-}\text{pathlength}\text{.}\end{array}$
