1. The problem statement, all variables and given/known data

How can I calculate the enthalpy of solution for sulfuric acid at 30°C/68°F, for 0,2;0,5;1 mol/kg?

2. Relevant equations



3. The attempt at a solution
I tried using a enthalpy-concentration diagram, but I cannot read it. I would apreciate if anyone could help me!

what is this diagram you have? what data are you provided with?

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