A Chemist Wishes to Calibrate a Bomb Calorimeter, So He

A chemist wishes to calibrate a bomb calorimeter, so he combusts 7.529 g of D-galactose, Δ_combustionU = -15.48 kJ g^-1, which causes a temperature change from 26.38 °C to 34.60 °C. What should the chemist report for the value of C_cal?

A) 24.34 kJ °C^-1
B) 8.009 kJ °C^-1
C) 14.18 kJ °C^-1
D) 16.67 kJ °C^-1
E) 9.170 kJ °C^-1
