How many moles of ions are there per mole of Al2 SO4 3?
For every mole of the ionic compound, there are 2 moles of aluminum and 3 moles of sulfate ions.
How many molecules are there in Al2 SO4 3?
Answer: In this case, Al2 means 2 aluminums, (SO4)3 means 3 (SO4)s. The parentheses mean that the 3 has to be multiplied by whatever number of atoms you have of each element inside: 3×1 sulfurs, 3×4 oxygens. Now for the grand tally: 2 aluminum atoms + 3 sulfur atoms + 12 oxygen atoms = 17 atoms total in each molecule.
What is the charge of SO4 3?
Al has a 3+ charge, and SO4 has a 2– charge.
