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
