Chapter 3.4, Problem 3.12AFP

Interpretation Introduction

Interpretation: A mixture of iron (III) oxide and aluminum powder is known as thermite was used to weld railroad tracks. The spectacular reaction of it forms aluminum oxide and molten iron. The number of moles of iron (III) oxide that are needed to form $\text{3}\text{.60}\times {\text{10}}^3$ moles of iron is to be interpreted.

Concept Introduction:

The mathematical expression of the mole concept can write as:

  $\text{Mole =}\frac{\text{Mass}}{\text{Molar mass}}$

1 mole of any substance contains $\text{6}\text{.022 }\times {\text{ 10}}^{\text{23}}$ number of particles or atoms or molecules.
