A student constructs a coffee cup calorimeter and places 50.0 mL of water into it. After a brief period of stabilization, the temperature of the water in calorimeter is determined to be 19.9 °C. To this is added 50.0 mL of water that was originally a temperature of 54.2 °C. A careful plot of the recorded temperature established T0 as 31.9 °C. What is the calorimeter constant (J/°C)?
