A **bomb calorimeter**, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy available from foods.Since the "bomb" itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as **calibrating** the calorimeter.In the laboratory, a student burns a **0.983-g** sample of **glutaric acid (C₅H₈O₄)** in a bomb calorimeter containing **1170. g** water. The temperature increases from **24.10 °C** to **26.90 °C**. The specific heat capacity of water is **4.184 J g⁻¹ °C⁻¹**.The combustion enthalpy is **–2151 kJ/mol** glutaric acid.\[ \text{C}_5\text{H}_8\text{O}_4(s) + 5 \text{O}_2(g) \longrightarrow 5 \text{CO}_2(g) + 4 \text{H}_2\text{O}(l) \quad \Delta H^\circ = -2151 \text{ kJ/mol} \]**Calculate the heat capacity of the calorimeter.**\[\text{heat capacity of calorimeter} = \boxed{\hspace{20mm}} \, \text{J/°C}\]
