Bomb calorimeter

4.184g of benzoic acid was burnt in bomb calorimeter. The rise in the temperature is 10^@ . The heat capacity of calorimeter and its contents is 2.644 kcal K^(-1) . Calculate the heat of combustion of benzoic acid.

Heat of combustion of benzoic acid (C_(6)H_(5)COOH) at constant volume at 25^(@)C is -3233 kJ/mole. When 0.5 g of benzoic acid is burnt in bomb calorimeter, the temperature of calorimeter increased by 0.53^(@)C . Now in the same bomb calorimeter 1g of C_(2)H_(6) burnt then temperature increased by 2.04 C . DeltaH for combustion of C_(2)H_(6) is

Heat of combustion of benzoic acid (C_6H_5COOH) at constant volume at 25^@C is -3233KJ//"mole" . When 0.5g of benzoic acid is burnt in bomb calorimeter, the temperature of calorimeter increased by 0.53^@C . Now in the same bomb calorimeter 1g of C_2H_6 burnt then temperature increased by 2.04^@C . DeltaH for combustion of C_2H_6 is

A 1.250 g sample of octane (C_(8)H_(18)) is burned in excess of oxygen in a bomb calorimeter. The temperature of calorimeter rises from 294.05 K to 300.78 K . If heat capacity of the calorimeter is 8.93 kJ K^(-1) , find the heat transferred to calorimeter.
