Chapter 4, Problem 117IAE

Interpretation Introduction

Interpretation:

Mass percentage of copper in the given mixture should be calculated.

Concept introduction:

One mole of cupric chloride and one mole of ferric chloride react with 2 and 3 moles of silver nitrate respectively.

Molarity is defined as the ratio of number of moles to the volume of solution in L. The mathematical expression is given by:

$\text{Molarity=}\frac{\text{number of moles}}{\text{volume of solution in L}}$

Mass percentage is defined as the ratio of mass of the element to the total mass of compound or sample and multiplies by 100. The mathematical expression is given by:

Mass percentage = $\frac{\text{Mass of element}}{\text{Total mass of compound}}\text{×100}$
