Question

Equal volumes, 50.0 mL, of 0.54897 M solution of HCl and 0.9573 M NaOH solutions having an initial temperature of 18.5 °C react in a coffee-cup calorimeter. The resultant solution records a temperature of 22.9 °C. Since the solutions are mostly water, the solutions are assumed to have a density of 1.0 g/mL and a specific heat of 4.184 J/g °C. The heat capacity of the calorimeter is 1.0 x 101 J/°C. Calculate the heat gained or released by the solution at constant pressure in J.
