In a constant-pressure calorimeter, 50.0 mL of 0.340 M Ba(OH)2 was added to 50.0 mL of 0.680 M HCl. The reaction caused the temperature of the solution to rise from 23.69 °C to 28.32 °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.

q = mass H2O x specific heat H2O x (Tfinal-Tinitial)
q/mol = delta H for 2 mols H2O. Divide by 2 for J/mol.
