Suppose you are investigating the reaction: M(s) + 2 HCl(aq) MCl2(aq) + H2(g).

You weigh out a 0.218 gram piece of metal and combine it with 73.6 mL of 1.00 M HCl in a coffee-cup calorimeter. If the molar mass of the metal is 41.47 g/mol, and you measure that the reaction absorbed 196 J of heat, what is the enthalpy of this reaction in kJ per mole of limiting reactant?

Enter your answer numerically to three significant figures in units of kJ/mol.
