A 0.582-g sample of Mg reacts with excess 1.0 M HCl (60.0 mL) according to the procedure used in this experiment. The initial and final temperatures were 24°C and 68°C. What is the ∆H of the reaction per mole of magnesium? Assume that the specific heat capacity for the solution is 4.187 J/oC∙g and that the density of the 1.0 M HCl is 1.00 g/mL.

4.187 J/oC∙g is incorrectly inputted as 4.184 J/g deg C
SHould be 4.187J, not 4.184J, so I'm not sure this is correct.
