An iron calorimeter of mass 153 g contains 260 g of water. The system is in thermal equilibrium at +10°C. We place two blocks of metal in the water: one is a 45 g piece of copper with an initial temperature of +61°C; the second piece has a mass of 75 g and is initially at +100°C. The combined system reaches a final equilibrium temperature of +41°C. Calculate the specific heat capacity of the unknown second piece of metal.
