A slice of banana weighing `2.502 g` was burnt in a bomb calorimeter producing a temperature rise of `3.05^(@)C`. The combustion of `0.316g` of benzoic acid in the same calorimeter produced a temperature rise of `3.24^(@)C`. The heat of combustion of benzoic acid at constant volume is `-3227 kJ mol^(-1)` . If average banana weigh `125g`, how many calories can be obtained from one average banana ?
