You place 30.4 ml of 0.23 M Ba(OH)2 in a coffee-cup calorimeter at 25.00°C and add 64.4 ml of 0.528 M HCl, also at 25.00°C. After stirring, the final temperature is 29.14°C. {assume that the total volume is the sum of the individual volumes and that the final solution has the same density (1.00 g/ml) and specific heat capacity (4.184 J/g°C) as water}. Calculate the change in enthalpy, Δ H, of the reaction (in kJ/mol) of water formed. Enter the appropriate sign (+/-). Enter to 1 decimal place.
