When 80.4 moles of calcium acetate are
dissolved in enough water to make 222.2
milliliters of solution, what is the molarity of acetate ions?
Answer in units of M

I already tried moles/liter and it was wrong

    I expect you calculated M Ca(Ac)2. Take your answer for mols Ca(Ac)2 and multiply by 2 to find mols Ac^-.
    (80.4/0.2222)*2 = ? and watch the number of significant figures.
