I am having trouble with a thermochemistry problem involving a calorimeter:

1) An electrical heater is used to add 20.50 kJ of heat to a constant-volume calorimeter. The temperature of the calorimeter increases by 4.88 degrees C. When 1.75 g of ethanol (C2H5OH) is burned in the same calorimeter, the temperature increases by 12.37 degrees C. Calculate the molar heat of combustion for ethanol.

any help would be greatly appreciated.

Start by calculating the water equivalent of the calorimeter.
(use the first part of question)

I found the heat capacity of the calorimeter, if that is what you meant. Can anyone elaborate on this problem more?
