Chapter 7, Problem 7.152CQ

(a)

Interpretation Introduction

Interpretation: The number of moles of ${\mathrm{Cl}}_2$needed should be calculated.

Concept Interpretation: The relation between number of moles and mass of any substance is as follows:

  $n=\frac{m}{M}$

Here, m is mass in grams and M is molar mass is g/mol.

(b)

Interpretation Introduction

Interpretation: The mass of ${\text{AlCl}}_{\text{3}}$should be calculated.

Concept Interpretation: The relation between number of moles and mass of any substance is as follows:

  $n=\frac{m}{M}$

Here, m is mass in grams and M is molar mass is g/mol.

(c)

Interpretation Introduction

Interpretation: The mass of ${\text{AlCl}}_{\text{3}}$should be calculated.

Concept Interpretation: The relation between number of moles and mass of any substance is as follows:

  $n=\frac{m}{M}$

Here, m is mass in grams and M is molar mass is g/mol.

(d)

Interpretation Introduction

Interpretation: The percent yield should be calculated.

Concept Interpretation: The relation between number of moles and mass of any substance is as follows:

  $n=\frac{m}{M}$

Here, m is mass in grams and M is molar mass is g/mol.

The reactant that limits the amount of product formed in the reaction is known as limiting reactant. The amount of product formed from limiting reactant is known as theoretical yield. The percent yield can be calculated as follows:

  $\%\text{yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100\%$
