Chapter 3, Problem 71E

Interpretation Introduction

Interpretation: The mass of ${\text{NH}}_4{\text{ClO}}_4$ that is used in the fuel mixture for every $1\text{kilogram}$ of $\text{Al}$ is to be calculated.

Concept introduction: One mole of any substance is equivalent to the atomic or molar mass of that substance.

Stiochiometric coefficient exists in a balanced chemical reaction represents the number of moles of that substance ( atoms/ molecule and ion ) present in that chemical reaction, as illustrated below.

  $\text{aA}+\text{bB}\to \text{cC}+\text{dD}$

Here, $\text{A, B, C}$ and $\text{D}$ are reacting species. On the other hand, $\text{a, b, c}$ and $\text{d}$ are stoichiometric coefficient which are also equivalent to the number of moles of each reacting species.
