Chapter 9, Problem 88E

Interpretation Introduction

Interpretation:

The STP volume of ${\text{CO}}_{\text{2}}$ gas produced from the combustion of $\text{10}\text{.0}\text{g}$ of propane, ${\text{C}}_{\text{3}}{\text{H}}_{\text{8}}$ is to be calculated.

Concept introduction:

Chemical reactions are represented by chemical equations. In a chemical equation the reactants are represented on the left of the arrow while the products are represented on the right of the arrow.

Stoichiometric coefficient is the number preceding each symbol in a reaction which determines the moles of the reactants and products in the reaction.

According to Avogadro’s hypothesis, at same pressure and temperature conditions, equal volume of the gases contains same amount of gas particles. At standard temperature and pressure conditions, $\text{1}\text{mol}$ of gas occupies a volume equal to $\text{22}\text{.4}\text{L}$.
