Question

The Starship Enterprise is caught in a time warp and Mr. Spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. The 307-g sample was heated to 98.7°C and placed into a calorimeter containing 72.4 g of water at 23.6°C. The heat capacity of the calorimeter was 15.7 J/K. The final temperature in the calorimeter was 32.4°C. What is the specific heat capacity of the mineral?

a. None of these choices is correct. b. 0.145 J/(g·K) c. 0.138 J/(g·K) d. 0.124 J/(g·K) e. 0.131 J/(g·K)
