In a constant-pressure calorimeter, 70.0 mL of 0.330 M Ba(OH)2 was added to 70.0 mL of 0.660 M HCl. The reaction caused the temperature of the solution to rise from 21.27 °C to 25.77 °C. If the solution has the same density and specific heat as water, what is ÄH for this reaction (per mole of H2O produced)? Assume that the total volume is the sum of the individual volumes.
