The burning of 2.051 g glucose, C6H12O6, in a bomb calorimeter causes the temperature of the water to increase from 24.92 to 31.41 °C. The bomb calorimeter assembly has a heat capacity of 4.912 kJ/°C. What is the heat of combustion of the glucose expressed in kJ/mol C6H12O6? (1) +2.80x10^3 kJ (2) -2.80x10^3 kJ (3) -15.6 kJ (4) +65.4 kJ (5) -65.4 kJ The correct answer is B, however,
