Question

Consider the reaction: Fe2O3+2Al=Al2O3
How many grams of Al are necessary to make 100.2 grams of Al2O3?
mols Al2O3 = ?
Convert mols Al2O3 to mols Al
Convert mols Al to grams Al. See your post above if you need refreshing. Same process. All of these stoichiometry problems are done the same way.
