A 54.2 g sample of an unknown metal is heated to 48.00 degrees Celsius.
It is then placed in a coffee-cup calorimeter filled with water.
The calorimeter and the water have a combined mass of 183.1 g and an overall specific heat of 1.34 cal/g•°C.
The initial temperature is 10.2°C when the metal is added.
The system reaches a final temperature of 23.00 °C.
