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.
