No, the answer is 2.22 grams.

1.11 is the number of mols H2 which you calculated correctly. Then you converted 1.11 mols to grams by

1.11 mols H2 x molar mass H2 = 1.11 mols x 2 g/mol = 2.22 grams H2 produced by 20 g Al. You did that correctly, also. The ONLY thing you didn't do is to show that Al was the limiting reagent and not H2SO4 (since both a quantity of Al AND a quantity of H2SO4 were given.)

ok thank you very much for your help
