An "ice calorimeter" can be used to determine the specific heat capacity of a metal. Suppose you heat a 50.0 g piece of silver to 99.8 deg C and then drop it onto ice. Once the metal's temp has dropped to 0 degrees C it is found that 3.54 g of ice has melted. What is the specific heat capacity of silver?
