Chapter 9, Problem 9PE

(a)

Interpretation Introduction

Interpretation:

The moles of water produced from $25$ moles of carbon dioxide have to be given.

Concept Introduction:

Mole ratio:

A mole ratio is a ratio between the numbers of moles of any two species involved in a chemical reaction.

Example,

In the reaction, ${\text{2H}}_{\text{2}}{\text{+O}}_{\text{2}}\stackrel{}{\to }{\text{2H}}_{\text{2}}\text{O}$, the mole ratio can be written as $\frac{\text{2}\text{mol}{\text{H}}_{\text{2}}}{\text{1}\text{mol}{\text{O}}_{\text{2}}}.$

(b)

Interpretation Introduction

Interpretation:

The moles of ${\text{CH}}_{\text{4}}$ produced from $12$ moles of water have to be given.
