In a constant-pressure calorimeter, 55.0mL of 0.310 M Ba(OH)2 was added to 55.0mL of 0.620 M HCL. The reaction caused the temperature of the solution to increase from 22.82 °C to 27.04 °C. If the solution has the same density as well as specific heat as water, explain what is ΔH for this reaction per mole of H2O produced? Presume that the total volume is the sum of the individual volumes.
