A calorimeter contains 82.4 grams of water at 20.9 °C. A 156 -gram piece of an unknown metal is heated to 81.9 °C and dropped into the water. The entire system eventually reaches 26.6 °C. Assuming all of the energy gained by the water comes from the cooling of the metal—no energy loss to the calorimeter or the surroundings—calculate the specific heat of the metal. The specific heat of water is 4.18 J/g · °C _____J/g · °C
