given the reaction: 2 Al + 3 H2SO4 -> Al2(SO4)3 + 3 H2
what volume of H2 gas measured at STP will be produced from 5.4 grams of AL reacting with an excess of H2SO4?
This is a stoichiometry problem. Here is a solved example of a stoichiometry problem. Just follow the steps.
After you have moles H2, use PV = nRT to convert moles to volume.
