Question

50 mL of HCL and 50 mL of 0.9998 M NaOH were mixed together in a calorimeter. The initial temp. of both the acid and base was 21.9 C. AT the end of the acid-base reaction, the temperature of the mixture increased to 27.8 C. At the end of the reaciton, the mixture was foudn to be acidic. Calculate the heat capacity of the calorimeter given that heat capacity of the acid and base solutions is 4.16 J (C) ^-1 per mL at room temperature and delta H is -58400J/mol.
