Calorimetry: A 360-g metal container, insulated on the outside, holds 180.0 g of water in thermal equilibrium at 22.0°C. A 24.0-g ice cube, at the melting point, is dropped into the water, and when thermal equilibrium is reached the temperature is 15.0°C. Assume there is no heat exchange with the surroundings. For water, the specific heat capacity is 4190 J/kg ? K and the heat of fusion is 3.34 × 105 J/kg. What is the specific heat capacity of the metal of the container?

A. 1700 J/kg ? K
B. 970 J/kg ? K
C. 2300 J/kg ? K
D. 2800 J/kg ? K
E. 3300 J/kg ? K
