The Starship Enterprise is caught in a time warp and 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) 0.124 J/(g ? K)
B) 0.131 J/(g ? K)
C) 0.138 J/(g ? K)
D) 0.145 J/(g ? K)
E) None of these choices is correct.
