Chapter 9, Problem 66E

Cavendish prepared hydrogen in 176G by the novel method of passing steam through a red-hot gun barrel:

$4{\text{H}}_2\text{O}\left(g\right)+3\text{Fe}\left(s\right)\to 3{\text{Fe}}_3{\text{O}}_4\left(s\right)+4{\text{H}}_2\left(s\right)$

(a) Outline the steps necessary o answer the following question: What volume of ${\text{H}}_2$ at a pressure of 743 torr and a temperature of 20 °C can be prepared from the reaction of 13.0 g of ${\text{H}}_2\text{O}$?

(b) Answer the question.
