Chapter 23, Problem 14QP

Interpretation Introduction

Interpretation:

The time required (in hours) to dissolve the given mass of the copper anode and electroplate it onto the cathode is to be calculated.

Concept introduction:

The number of moles of a substance is the ratio of the mass of the substance to the molar mass of the substance.

The number of moles of a substance is represented as follows:

$\text{Moles}=\frac{\text{mass}}{\text{Molar mass}}$

The relation between current and charge is expressed as follows:

$\text{Charge}=\text{current}\times \text{time}$
