Chapter 10, Problem 81E

Interpretation Introduction

Interpretation:

The mass of $9.6\%$ by mass of $\text{NaCl}$ solution required to obtain $105\text{kg}$ of chlorine by the electrolysis of salt water is to be calculated.

Concept introduction:

The stoichiometry of a chemical species involved in a chemical reaction represents the number of chemical species involved in the chemical reaction. The stoichiometry of a chemical species helps in calculating the expected mass of reactant and product. The stoichiometry of a chemical species is also represented by number of moles. The number of moles of a substance is given by the expression shown below.

$\text{n}=\frac{\text{m}}{\text{M}}$
