A 48.79 g sample of metal is heated to 98.77oC and then quickly transferred to 88.34 mL of water at 24.65oC contained in a new calorimeter. This calorimeter has a calorimeter constant (heat capacity) with a numerical value of 55.7 (see problem 2e above for appropriate units). The thermal equilibrium temperature of the metal sample plus water mixture was 27.49oC. Assume the density of the water is 1.00 g/mL.

a. How much heat in Joules is gained by the water? Report your answer to three significant figures.

b. How much energy in Joules is gained by the calorimeter? Report your answer to three significant figures.

c. How much energy in Joules is lost by the metal. Report your answer to three significant figures as a negative value.

d. What is the specific heat of the metal to three significant figures?

e. What are the units for the specific heat of the metal?
