The reaction of 0.130 moles of a metal with an acidic aqueous solution in a calibrated calorimeter causes the temperature to increase by 49.0°C. The mass of the final solution is 72.0 grams, and its heat capacity is 3.85 J/g°C; the heat capacity of the calorimeter is 5.0 J/°C. Calculate the ΔHreaction in kJ/mol metal.
