Answer to Question #56897 in Molecular Physics | Thermodynamics for Buono11

Question

A 28.45 g metal specimen of gold and 25.75 g metal specimen of iron, each at a temperature of 100.0 °C were dropped into 570.0 mL of water at a temperature of 17.70 °C. The molar heat capacity of iron and gold are 25.19 J mol -1 °C -1 and 25.41 J mol 1 °C -1 respectively. Assume the density of water to be 1.00g/mL, what is the final temperature of the water and pieces of metals?
