Consider the reaction: M + 2HCl → MCl2 + H2

When 0.25 mol of the metal, M, reacted with an aqueous HCl solution (the HCl is in excess), the temperature of the solution rose because the reaction produced 5990 J of heat. What is ?H in kJ per mol of M for this reaction? (Hint: Is this reaction exothermic or endothermic?) 

It is possible that your answer could be either positive or negative. If it is negative, you must include the "minus" sign. Enter your answer as a decimal number. 

 kJ/mol
