30.00 mL of 0.500 M NaOH is placed in a coffee-cup calorimeter at 22.00°C. 25.00 mL of 0.500 M HCl, also at 22.0°C, is then carefully added. After stirring, the final temperature is 26.1°C. Calculate the molar heat of neutralization (in kJ mol-1). The heat capacity of the calorimeter is 10 cal/g·0C.
