Alum is the common name for aluminum potassium sulfate or aluminum sulfate.
4,12 grams aluminum sulfate is equivalent to 0,012 moles (for the anhydrous salt).
aluminum trisulfide
Aluminum Sulfate is Al2 SO4 (aluminum, sulfur, and oxygen)
Formula: K2SO4
aluminium sulfate

Al2(SO4)3 + 3Ca → 3CaSO4 + 2Al Aluminum sulfate + calcium → Calcium sulfate + aluminum
1 formula unit of aluminum sulfate has the formula Al2(SO4)3. So there are 2 atoms of aluminum, 3 atoms of sulfur and 12 atoms of oxygen in 1 formula unit of aluminum sulfate. There are no molecules of aluminum sulfate. They are called formula units.
There are 3 ions in the formula Al2SO4 (2 aluminum and 1 sulfate), but this formula is wrong. The formula of aluminum sulfate is Al2(SO4)3 which contains 5 ions: 2 aluminum ions and 3 sulfate ions.
