In a constant-pressure calorimeter, 65.0 mL of 0.330 M Ba(OH)2 was added to 65.0 mL of 0.660 M HCl. The reaction caused the temperature of the solution to rise from 21.91 °C to 26.41 °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.

Ba(OH)2 + 2HCl ==> 2H2O + BaCl2
q = mass H2O x specific heat H2O x (Tfinal-Tinitial) = delta H.
mols HCl = 0.065 x 0.660 = 0.0429 mols
delta H in J/mol = q/0.0429 = ?
