A 5.1-gram piece of gold jewelry is removed from water at 100.0°C and placed in a coffee- cup calorimeter containing 16.9 g of water at 22.5°C. The equilibrium temperature of the water and jewelry is 23.2°C. The calorimeter constant is known from calibration experiments to be 1.87 J/°C. What is the specific heat of this piece of jewelry? The specific heat of pure gold is 0.129 J/g °C. A 5.1-gram piece of gold jewelry is removed from water at 100.0°C and placed in a coffee- cup calorimeter containing 16.9 g of water at 22.5°C.
