The reaction caused the temperature of the solution to rise from 24.18 ? to 28.54 ??" the solution has the same density and specific heat as water (1.00 g/mL and 4.184 Jig "C, respectively), what is AH for this reaction (per mole of H20 produced)?

Total solution weight = 120 g
q = mc(Tf - Ti) = 120 g x 4.184 J g-1oC-1 x (28.54 - 24.18) oC
q = 2189 J
No. of moles of Barium hydroxide = 0.320 mol/L x 0.06 L = 0.0192 mol
So 0.0192 mol barium hydroxide produces 2189 J
1 mol of barium hydroxide produces heat = 2189 J / 0.0192 mol = 114 kJ/mol
But 1 mol of barium hydroxide produces 2 mol water. So heat released for 1 mol water = 114 / 2 = 57.0 kJ/mol
