How many grams of hydrogen gas can be produced by the reaction of 27.0 g of Al ( 26.981538 g/mol) with an excess of dilute hydrochloric acid? to do this, you will need to write the balanced chemical reaction first!

Al + HCl-----> H2 + AlCl3

so (27.0g of Al) / (26.98g/mol)

multiply by the molar mass of H which is about 1 so thats pretty simple
