You should use care when dissolving H_2SO_4 in water because the process is highly exothermic. To measure the enthalpy change, 4.5 g of concentrated H_2SO_4 (l) was added (with stirring) to 148 g of water in a coffee-cup calorimeter. This resulted in an increase in temperature from 20.8 degree C to 27.7 degree C. Calculate the enthalpy change for the process H_2SO_4 (l) rightarrow H_2SO_4(aq), in kJ/mol. Assume the specific heat capacity of the solution is 4.2 J/g K. Enthalpy...
