Question- You place 0.0500 g of Mg chips in a coffee-cup calorimeter. You add 100.0 mL of 1.00 M HCl at a temperature of 22.21 degrees C. After the reaction is complete, the water temperature goes up to 24.46 degrees C. Assuming the specific heat capacity of the solution is 4.20 J/g-C and the density of the solution is 1.00 g/mL, Calculate enthalpy per mole of Mg for the reaction. MM of Mg = 24.305 g/mol

Illustrate structures to prove your interpretation.
