A chemistry student wants to determine the specific heat capacity of an unknown metal. The student performs a calorimetry experiment and records the following data: - 50 mL of water at 25°C was added to a calorimeter. - The initial temperature of the metal was 100°C. - The final temperature of the metal and water mixture was 30°C. - The mass of the metal was 100 grams.What is the specific heat capacity of the metal?
