A piece of iron with a mass of 56.2 grams is heated and placed into a calorimeter containing 93.64 grams of water at 7.0 degrees Celsius. The final temperature of the water and the iron is 90.5 degrees Celsius. Assuming no heat is lost to the surroundings, how much heat (in Joules) does the iron release? Round your answer to the nearest 0.1 Joules.
