Chapter 10, Problem 73E

Interpretation Introduction

Interpretation:

The mass of oxygen that can be produced from emergency oxygen masks which contain $125\text{ g}$ of ${\text{KO}}_{\text{2}}$ is to be calculated.

Concept introduction:

The stoichiometry of a chemical species involved in a chemical reaction represents the number of chemical species involved in the chemical reaction. The stoichiometry of a chemical species helps in calculating the expected mass of reactant and product. The stoichiometry of a chemical species is also represented by number of moles. The number of moles of a substance is given by the expression shown below.

$n=\frac{m}{M}$
