Chapter 13, Problem 96E

Interpretation Introduction

Interpretation:

The molarity of zinc chloride $\left({\text{ZnCl}}_2\right)$ is to be calculated when $\text{Zn}$ completely reacts with $\text{CuCl2}$.

Concept Introduction:

Molarity can be defined as the number of moles of solute per liter of solution.

Mathematically, molarity $\left(\text{M}\right)$ is calculated by the formula as follows:

$\text{M=}\frac{\text{Moles solute}}{\text{Liters solution}}$…… (1)

The volume of solution will be in liters.

The relation between numbers of moles $\left(n\right)$ and molar mass is as follows:

$n=\frac{m}{\text{molar mass}}$…… (2)

Here, $m$ is mass.
