9. A 730 g piece of copper is heated in a furnace to a temperature T. The copper is then inserted into a 165 g copper
calorimeter containing 265 g of water. The initial temperature of the water and calorimeter is 19 °C, and the final
temperature after equilibrium is established is 40 °C. When the calorimeter and its contents are weighed, 31.0 g of water
are found to have evaporated. What was the
