Chapter 3, Problem 92E

Interpretation Introduction

Interpretation:

The given question stated that a Freon leak in the air conditioning system of a large building releases $17\text{kg}$ of ${\text{CHF}}_2\text{Cl}$ per month. If the leak continues, the mass $\left(\text{in}\text{kg}\right)$ of chlorine released into the atmosphere in each year is to be calculated.

Concept introduction: The formula to calculate formula mass is,
   $\text{Formula}\text{mass}=\left({\text{N}}_{\text{1}}\times {\text{x}}_{\text{1}}\right)+\left({\text{N}}_{\text{2}}\times {\text{x}}_{\text{2}}\right)+\mathrm{...}+\left({\text{N}}_{\text{n}}\times {\text{x}}_{\text{n}}\right)$

The number of moles is calculated by the formula,
   $\text{n}=\frac{\text{m}}{{\text{M}}_{\text{w}}}$

To determine: The mass of chlorine released into the atmosphere in one year.
