5 In order to determine the heat capacity of their latest phone, CrabappleTM engineers cool the phone in the freezer to -31.7ºC. They then drop it into a calorimeter with some water in it that is at a temperature of 50.8ºC. The calorimeter (including the water) has a total heat capacity of 869.42 J/ºC. After a few minutes the temperature of the calorimeter is stabilized to 31ºC. What is the heat capacity of the phone? Enter your answer with at least 3 sig figs assuming units of J/ºC.
