For 8.23, why do we ignore the number of moles in q=nCdeltaT?

Also for this question why do we ignore the heat used to raise the temperature of the water?

For reference, the question is: A calorimeter was calibrated with an electric heater, which supplied 22.5 kJ of energy as heat to the calorimeter and increased the temperature of the calorimeter and its water bath from 22.45C to 23.97C. What is the heat capacity of the calorimeter?

Are there any examples of how to calculate empathy changes from calorimetric data?
