How much bauxite (Al2O3) would you have to mine if you wanted to obtain 100.0 g Al metal from the ore?

4Al + 3O2 ==> 2Al2O3
mols Al you want = grams/atomic mass Al.
Using the coefficients in the balanced equation, convert mols Al to mols Al2O3.
Then grams Al2O3 = mols Al2O3 x molar mass Al2O3.
This assume bauxite is pure Al2O3 and it isn't. Actually this is not a good answer.
