In a constant-pressure calorimeter, 50.0 mL of 0.300 M Ba(OH)2 was added to 50.0 mL of 0.600 M HCl. The reaction caused the temperature of the solution to rise from 24.50 degrees C to 28.59 degrees C. If the solution has the same density and specific heat as water, what is delta H for this reaction (per mole of H2O produced)? Assume that the total volume is the sum of the individual volumes. Delta H = ___ kJ/mol H2O
