How many joules were liberated by the reaction

Question

Toluene, C₇H₈, is used in the manufacture of explosives such as TNT (trinitrotoluene). A 1.500 g sample of liquid toluene was placed in a bomb calorimeter along with excess oxygen. When the combustion of the toluene was initiated, the temperature of the calorimeter rose from 25.000 °C to 26.413 °C. The products of the combustion were CO₂(g) and H₂0(1), and the heat capacity of the calorimeter was 45.06 kJ °C^-1

(a) Write the balanced chemical equation for the reaction in the calorimeter.

(b) How many joules were liberated by the reaction?

(c) How many joules would he liberated under similar conditions if 1.000 mol of toluene was burned?
