    The molar mass of Mn(SO₄)₂ is 247.0645 g/mol!

    To prepare a 12 M solution you would have to dissolve 2964 g of it in a final volume of 1000 ml. Seems to be impossible to me.

    But anyway, each Mn-Sulfate splits into 1 Mn⁴⁺ and two SO₄²⁻ ions. So sulfate ion concentration will be always twice the Mn(SO₄)₂ concentration on molar basis. 24 M is the right answer.
