    Answer:

    0.716

    Explanation:

    First, write the balanced equation:

    3 H2CO3 + 2 Fe(OH)3 —-> Fe2(CO3)3 + 6 H2O

    Second, go from the molarity of H2CO3 to liters of Fe(OH)3

    (Pull mole ratio from balanced equation)

    1.22/1L  x  0.0880/1  x  3molH2CO3/2molFe(OH)3 x 1/0.225L

    Use calculator, and you end up with 0.7157333

    Round to 0.716
