Chapter 4, Problem 4.22NP

A 0.1429 g sample of sucrose ${\text{C}}_{\text{12}}{\text{H}}_{\text{22}}{\text{O}}_{\text{11}}$ is burned in a bomb calorimeter. In order to produce the same temperature rise in the calorimeter as the reaction, 2353 J must be expended.

1. Calculate $\Delta U$ and $\Delta H$ for the combustion of 1 mole of sucrose.
2. Using the data tables $\Delta U$ and $\Delta H$ your answer to (a), calculate $\Delta H_f^{°}$ for sucrose.
3. The rise in temperature of the calorimeter and its contents as a result of the reaction is 1.743 K. Calculate the heat capacity of the calorimeter and its contents.
