A 50.00 g sample of an unknown metal is heated
to 45.00°C. It is then placed in a coffee-cup
calorimeter filled with water. The calorimeter and
the water have a combined mass of 250.0 g and
an overall specific heat of 1.035 cal/g•°C. The
initial temperature of the calorimeter is 10.00°C.
The system reaches a final temperature of
11.08°C when the metal is added.
