A quantity of 4.00 102mL of 0.600 M HNO3 is mixed with 4.00 102mL of 0.300 M Ba(OH)2 in a constant-pressure calorimeter of negligible heat capacity. Explain the initial temperature of both solutions is the same at 14.66°C. Explain what is the final temperature of the solution? Presume that the densities and specific heats of the solutions are the same as for water 1.00 g/mL and 4.184 J/g•°C, respectively. Use -56.2 kJ/mol for heat of neutralization.
