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 the calorimeter is determined to be 21.95 °C. To this is added 50.0 mL of water that was originally at 59.60 °C. A careful plot of the temperatures recorded after this established that the temperature at To was 37.55 °C. What is the calorimeter constant in J/oC for this calorimeter? (density H2O = 1.00 g/mL; specific heat of water = 4.184 J/g·°C) You mix 50.0 mL of a weak monoprotic acid with 50.0 mL of NaOH solution in a coffee cup calorimeter. Both solutions (and the calorimeter) were initially at 21.7 °C. The final temperature of the neutralization reaction was determined to be 34.1 °C. The calorimeter constant was known to be 20.8 J/°C. (specific heat of H2O = 4.184 J/ g·°C). What is the total amount of heat (in kJ) evolved in this reaction?
