Chapter 13, Problem 115E

Consider the reaction:

$2\text{Al}\left(s\right)+3{\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}\left(aq\right)\to {\text{Al}}_2{\left({\text{SO}}_{\text{4}}\right)}_3\left(aq\right)+3{\text{H}}_{\text{2}}\left(g\right)$

What minimum volume of $4.0\text{M}{\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ is required to produce 15.0 L of ${\text{H}}_{\text{2}}$ at STP?
