A 27.00 g piece of iron and a 20.20 g piece of gold at 100 degrees C were dropped into 680.0 mL of water at 16.35 degrees C. The molar heat capacities of iron and gold are 25.19 J/(mol x degrees C) and 25.41 J/(mol x degrees C), respectively. What is the final temperature of the water and pieces of metal?
