Chapter 9, Problem 5ST

Interpretation Introduction

Interpretation:

In the chemical reaction, $2{\text{H}}_{\text{2}}\text{O}\left(l\right)\to 2{\text{H}}_{\text{2}}\left(g\right)+{\text{O}}_{\text{2}}\left(g\right)$, the STP volume of hydrogen gas produced by decomposition of $\text{5}\text{.00}\text{g}$ of water is to be calculated.

Concept Introduction:

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 $\text{22}\text{.4}\text{L}$.
