Chapter 11, Problem 131QGW

A 14.22 g aluminum soda can reacts with hydrochloric acid to the reaction:

$2\text{Al}\left(s\right)+6\text{HCl}\left(aq\right)\to 3{\text{H}}_2\left(g\right)+2{\text{AlCl}}_3\left(aq\right)$

The hydrogen gas is collected by the displacement of water. What volume of hydrogen is collected if the external pressure is 749 mm Hg and the temperature is 31 °C, assuming that there is no water vapor present? What is the vapor pressure of water at this temperature? What volume do the hydrogen and water vapor occupy under these conditions?
