Chapter 8, Problem 89E

Interpretation Introduction

Interpretation:

The amount of oxygen gas in grams produced by the explosion of ammonium nitrate is to be determined.

Concept introduction:

In the balanced chemical reaction, moles of reactants and products must be equal. The reaction is balanced by the stoichiometry coefficient.

The amount of product produced is calculated by conversion of the initial amount of reactant to moles by the molar mass as the conversion factor.

The moles of products are calculated and are converted to the grams by the use of molar mass as the conversion factor.

Mass to mole conversion factor = $\frac{\text{number of moles of compound}}{\text{molar mass of compound}}$

Mole to mole conversion factor=$\frac{\text{number of moles of product}}{\text{number of moles of reactant}}$

Mole to mass conversion factor = $\frac{\text{molar mass of compound}}{\text{number of moles of compound}}$

For theoretical yield, steps are mass to mole conversion → mole to mole conversion → mole to mass conversion.
