We are asked what mass of H2 gas would be produced by the complete reaction of the aluminum block.
Molar mass Al = 26.98 g/mol
Molar mass H2 = 2.02 g/mol
Sulfuric acid dissolves aluminum metal according to the following reaction: 2 Al(s) + 3 H2SO4(aq) → Al2(SO4)3(aq) + 3 H2(g)
Suppose you wanted to dissolve an aluminum block with a mass of 15.2 g. What mass of H2 gas would be produced by the complete reaction of the aluminum block?
