Explanation / Answer

(A)

heat required = mass * specific heat capacity* change in temperature

thus specific heat capacity of the material = 55/(9.90*11.1) =0.501 J/g/C

(B)

9.9 g of silver = 9.9/108 = 0.092 moles of silver

now, heat required = moles *molar heat capacity*change in temperature

or, energy required = 0.092*25.35*13.3 = 30.906 J

(C)

molar heat capacity = molar mass* specific heat capacity

therefore specific heat capacity of silver = 25.35/108 = 0.235 J/g/C
