An analysis of aluminum sulfate revealed that its copper contained 0.0774 mole sulfate ions. So find the aluminum moles present in this sample.

Moles of SO4− ions in aluminium sulphate = 0.0774 mole
The molecular formula of aluminium sulphate is Al2(SO4)3
Al2(SO4)3 → 2Al3+ + 3SO42−
Therefore 2 moles of Al3+ combines with 3 moles of SO42− ions.
So, 0.0774 mols of SO42− ions will contain
Moles of aluminium are 0.516 mole
