Question 5
0.2 pts
Consider the reaction
C12H22011 (s) + 12 02 (8) - 12 CO2 (g) + 11 H20 (1)
in which 10.4 g of sucrose, C12H22011, was burned in a bomb calorimeter with a heat capacity of
7.50 kJ/C (including its water). The temperature inside the calorimeter was found to increase by
21.3 C. Based on this information, what is the heat of this reaction per mole of sucrose?
Enter your answer numerically, in terms of KJ/mol and to three significant figures.
D
Question 6
0.2 pts
When a 4.20 g sample of liquid octane (CH18) is burned in a bomb calorimeter, the temperature of
the calorimeter rises by 26.6 C. The heat capacity of the calorimeter, measured in a separate
experiment, is 6.10 kJ/.C. The calorimeter also contains 3.00 kg of water, specific heat capacity of
4.18 J/g C. Determine the heat of combustion of octane in units of kJ/mol octane.
Enter your answer numerically and in terms of KJ/mol.
