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.
