15.00 mL of .8000 mol/L solution of diprotic acid is mixed with 30.00mL of .6000 mol/L NaOH inside a coffee cup calorimeter. The initial temperature of the acid was 22.1 degrees Celsius and the initial temperature of the base was 22.1 degrees Celsius. after mixing, the temperature was 27.8 degrees Celsius. the density of the solution is assumed to be .998 g/mL.
What is q of surroundings for this reaction?
