Homework Help: CHEM

Posted by Akle on Friday, February 10, 2012 at 9:50pm.

I know I posted this question again but no one is really helping me. Can someone please help me as soon as possible.

In a constant-pressure calorimeter, 60.0 mL of 0.340 M Ba(OH)2 was added to 60.0 mL of 0.680 M HCl. The reaction caused the temperature of the solution to rise from 24.07 C to 28.70 C. If the solution has the same density and specific heat as water, what is ΔH for this reaction (per mole of H2O produced)? Assume that the total volume is the sum of the individual volumes.
