When 0.042 moles of aluminum sulfate are
dissolved in enough water to make 763
milliliters of solution, what is the molarity of sulfate ions?
Answer in units of M.

I wonder what is going on here? this is incredibly easy

Moles sulfate ions in Al2(SO4)3
Molarity= molessulfateions/liters of solution
= 3*.042/.763 moles/liter
