Question

A 93 g piece of copper is heated in a furnace to a temperature T. The copper is then inserted into a 150 g copper calorimeter containing 193 g of water. The initial temperature of the water and calorimeter is 16 °C, and the final temperature after equilibrium is established is 38 °C. When the calorimeter and its contents are weighed, 35.0 g of water are found to have evaporated. What was the temperature T?
