Heat of solution for sulfuric acid in water

In summary, the person is asking for help in calculating the enthalpy of solution for sulfuric acid at 30°C/68°F, for concentrations of 0.2, 0.5, and 1 mol/kg. They have attempted to use an enthalpy-concentration diagram but are having trouble interpreting it. They only have the concentration of H2SO4 and water and need to find the theoretical enthalpy of solution for comparison with experimental results.

This one: http://docs.google.com/gview?a=v&q=cache:sexRAoFSlI4J:www.norfalco.com/documents/NorFalco_H2SO4Property07.pdf+calculate+enthalpy+sulfuric+acid&hl=en&gl=br

The only data I got is the concentration of the solution H2SO4 and water. I needed to find the theoretical enthalpy of solution for this reaction, to compare with the results I got from the experiment.
