    Ans : The chemical formula for aluminum sulfate is Alâ‚‚ (SOâ‚„) â‚ 6.00 mol Alâ‚‚ (SOâ‚„) â‚ Al: 6.00 mol Alâ‚‚ (SOâ‚„) â‚ x (2 mol Al / 1 mol Alâ‚‚ (SOâ‚„) â‚) = 12.00 mol Al S: 6.00 mol Alâ‚‚ (SOâ‚„) â‚ x (3 mol S / 1 mol Alâ‚‚ (SOâ‚„) â‚) = 18.00 mol S O: 6.00 mol Alâ‚‚ (SOâ‚„) â‚ x (12 mol O / 1 mol Alâ‚‚ (SOâ‚„) â‚) = 72.00 mol O
