In a constant-pressure calorimeter, 50.0 mL of 0.340 M Ba(OH), was added to 50.0 mL of 0.680 M HCI. The reaction caused the temperature of the solution to rise from 22.91 °C to 27.54 °C. If the solution has the same density and specific heat as water (1.00 g/mL and 4.184J/g • °C,) respectively), what is AH for this reaction (per mole H,O produced)? Assume that the total volume is the sum of the individual volumes.
