During the electrolysis of molten aluminum chloride in an electrolytic cell, 5.40 g of aluminum is produced at the cathode. Predict the mass of chlorine produced at the anode.

Answer 1

This is just a stoichiometry problem. You don't need anything about electrolysis.
2AlCl3 ==> 2Al + 3Cl2

Convert g Al to mols.
Convert mols Al to mols Cl2.
Convert mols Cl2 to grams.
Check my thinking.
