A combustion bomb containing 5.417 g of aluminum metal and 15.974 g of iron III oxide is placed in an ice calorimeter that initially contained 7.746 kg of ice (at o degrees C) and 7.894 kg of liquid water (at o degrees C). The reaction, once ignited by remote control, forms pure iron and aluminum oxide. It is observed that the calorimeter contains 7.493 kg of ice and 8.147 kg of liquid water after the reaction. The heat of fusion of ice is 335 J/g. What is the enthalpy change for this reaction per mole of iron formed?

So far I have:

Al(s) + Fe2O3 (s) ----> AlO3 + 2Fe

am i supposed to include the ice and water in the balanced equation? what should i do next, i'm sort of lost.
