2. A student wishes to determine the heat capacity of a coffee-cup calorimeter. After she mixes 92.7 g of water at 68.7°C with 92.7 g of water, already in the calorimeter, at 20.8°C, the final temperature of the water is 35.0°C. Calculate the heat capacity of the calorimeter in J/K. Use 4.184 J/g°C as the specific heat of water.

Enter your answer to three significant figures in unit of J/K.
