The temperature increases from 24.9°C to 43.6°C when 1.25 g of calcium metal reacts with 150 mL of 5.50 M aqueous HBr. If the heat capacity of the calorimeter is 769 J/°C, the specific heat of the final solution is 4.18 J/(g·°C), and the density of the solution is 1.00 g/mL, what is the ΔH in kJ/mol for the reaction?
