Determine the enthalpy change for the process h2so4

Question

When dissolving the H₂SO₄ in water you should use care because the process is highly exothermic. To calculate the enthalpy change, 5.2 g H₂SO₄ (l) was added to 135 g of water in a coffee-cup calorimeter. This resulted in an increase in temperature from the 20.2 ^oC to28.8 ^oC. Determine the enthalpy change for the process H₂SO₄ (l) --> H₂SO₄ (aq), in kJ/mol.
