Chapter 1, Problem 1A.10P

Interpretation Introduction

Interpretation: The amount of ${\text{O}}_{\text{3}}$ (in moles) in the column with cross-sectional area of $\text{1}{\text{.00 dm}}^2$ for a typical midlatitude value, the number of moles of ozone found in a column of air above a $\text{1}{\text{.00 dm}}^2$ area with abundance below $\text{100}$ Dobson units, the average molar concentration corresponding to $\text{250}$ Dobson units and $\text{100}$ Dobson units has to be calculated.

Concept introduction: Ozone is a trace atmospheric gas and it plays a major role in shielding the atmosphere of Earth from the harmful UV rays.  The abundance of ozone is commonly expressed in Dobson units.  $\text{1 Du}$ is equals to $\text{0}{\text{.4462 mmol m}}^{-2}$.
