Sulfuric аcid dissоlves аluminum metаl accоrding tо the reaction: 2 Al(s) + 3 H2SO4(aq) → Al2(SO4)3(aq) + 3 H2(g) Suppose you want to dissolve an aluminum block with a mass of 25.0 g. What mass of H2 gas (in g) does the complete reaction of the aluminum block produce? Molar masses: Al = 26.98 g/mol, H2SO4 = 98.08 g/mol, H2 = 2.02 g/mol.
