Question:

Refer to Example 7-3. Based on the heat of combustion of sucrose established in the example, what should be the temperature change (ΔT) produced by the combustion of 1.227 g C12H22O11 in a bomb calorimeter assembly with a heat capacity of 3.87 kJ/°C?

Example 7-3

The combustion of 1.010 g sucrose, C12H22O11, in a bomb calorimeter causes the temperature to rise from 24.92 to 28.33 °C. The heat capacity of the calorimeter assembly is 4.90 kJ/°C. 

(a) What is the heat of combustion of sucrose expressed in kilojoules per mole of C12H22O11

(b) Verify the claim of sugar producers that one teaspoon of sugar (about 4.8 g) contains only 19 Calories.
