Chapter 9, Problem 57E

The heat capacity of a bomb calorimeter was determined by burning $\text{6}\text{.79 g}$ of methane (energy of combustion $\text{=}-{\text{802 kJ/mol CH}}_{\text{4}}$ ) in the bomb. The temperature changed by $\text{10}\text{.8°C}$ .

1. What is the heat capacity of the bomb?
2. A $\text{12}\text{.6-g}$ sample of acetylene $\left({\text{C}}_{\text{2}}{\text{H}}_{\text{2}}\right)$ produced atemperature increase of $\text{16}\text{.9°C}$ in the same calorimeter. What is the energy of combustion of acetylene(in $\text{kJ/mol}$)?
