Chapter 21.7, Problem 21.11BFP

Interpretation Introduction

Interpretation:

The required amount of current (in amperes) has to be calculated.

Concept introduction:

The relationship between charge and current to find the time needed.

  $\text{Time}\text{(s)}\text{=}\frac{\text{charge}\text{(C)}}{\text{current}\text{(A)}}$

The given current must flow

  $GramsofC{l}_2\Rightarrow molesofC{l}_2\Rightarrow molesof{e}^{-}\Rightarrow coulombs\Rightarrow \sec onds$
