Problem- Suppose that following the procedure of the Hess's Law experiment you had reacted a 0.950 g sample of MgO with 60.0 mL of 1.2 M HCl according to the reaction
MgO(s) + 2H+ ---> Mg2+ +H2O

The initial and final temperatures were 20.0 C and 43.0 C respectively. If you assume that the specific heat capacity of the solution was 4.184 J/degree-g and the density of the solution was 1.00 g/mL, what should you report for deltaHrxn (kJ/mol) for the above reaction?
