A quantity of 2.30 × 102 mL of 0.900 M HNO3 is mixed with 2.30 ×102 mL of 0.450 M Ba(OH)2 in a constant-pressure calorimeter ofnegligible heat capacity. The initial temperature of both solutionsis the same at 18.46°C. The heat of neutralization when 1.00 mol ofHNO3 reacts with 0.500 mol Ba(OH)2 is −56.2 kJ/mol. Assume that thedensities and specific heats of the solution are the same as forwater (1.00 g/mL and 4.184 J/g · °C, respectively). What is thefinal temperature of the solution? (in C)
