In a constant-pressure calorimeter, 60.0mL of 0.310 M Ba(OH)2 was added to 60.0 mL of 0.620 M HCl. The reaction caused the temperature of the solution to rise from 23.27 °C to 27.49 °C. If the solution has the same density and specific heat as water, what is PH for this reaction per mole of H2O produced? Presume that the total volume is the sum of the individual volumes.
