4 Having just invented a new type of calorimeter, Dr. Campbell 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 32.035 grams of water at a temperature of 83.2ºC to the calorimeter. After a few minutes the final temperature of the calorimeter stabilizes at 41.6ºC. 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.

A student has calibrated his/her calorimeter and finds the heat capacity to be 14.8 J/°C. S/he then determines the molar heat capacity of aluminum. The data are: 25.7 g Al at 100.0°C are put into the calorimeter, which contains 99.8 g H20 at 18.5°C. The final temperature comes to 22.6°C. Calculate the heat capacity of Al in J/mol-°C
