Under constant-volume conditions the heat of combustion of benzoic acid (C6H5COOH) is 26.38 kJ/g. A 1.640-g sample of benzoic acid is burned in a bomb calorimeter. The temperature of the calorimeter increases from 22.23ºC to 27.20ºC.
a) What is the total heat capacity of the calorimeter?
b)A 1.320-g sample of a new organic substance is combusted in the same calorimeter. The
temperature of the calorimeter increases from 22.14ºC to 26.82ºC. What is the heat ofcombustion per gram of the new substance?
c)Suppose that in changing samples, a portion of the water in the calorimeter weere lost. In what way, if any, would this change the heat capacity of the calorimeter?
