Having just invented a new type of calorimeter, Dr. Cox needs to determine the heat capacity of the calorimeter.  She carries out the following experiment to do this: She puts 20.0 grams of water in her empty calorimeter and it is allowed to stabilize at a temperature of 25.0ºC.  She then adds 33.948 grams of water at a temperature of 86.7ºC to the calorimeter.  After a few minutes the final temperature of the calorimeter stabilizes at 42.4ºC.   Based on this experiment, what is the heat capacity of her calorimeter assuming units of J/ºC? Enter your answer with at least 3 sig figs.
