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.

I worked this earlier for someone. I can look it up if you need it. Or do you just need to ask a question about it?
I solved it numerous times and it says I am getting the wrong answer. Could you help explain how to solve it and see what I am doing wrong please.
Also can you look it up as well thanks. I really appreciate it!
If you will post your work I will look at it.

This is my work.....
(18g) (4.184 J)(28.70-24.07)
I get 350.95
then i divide it by 0.0340 and get 10322.17. Then I divide it by a 1000 and get 10.322... It is wrong. Can you take a look at my work and tell me what i did wrong and confirm the right answer for me thanks!
