Chapter 4, Problem 4.85P

Interpretation Introduction

Interpretation:Respired air in liters that is reacted with $80.0\text{ g}$ of ${\text{Na}}_2{\text{O}}_2$ is to be determined.

Concept introduction:The quantity of species that gives the relation between reactants and products is determined by the stoichiometry of a reaction. Consider the general reaction,

  $\text{2A}+\text{B}\to 3\text{C}$

In the above reaction, two moles of $\text{A}$ reacts with one mole of $\text{B}$ to form three moles of $\text{C}$ . Therefore, stoichiometric ratio of A and B is $2:2$ , of A and C is $2:3$ and of B and C is $1:3$ .
