Aquantity of 5.70 × 102 ml of 0.800 m hno3 is mixed with 5.70 × 102 ml of 0.400 m ba(oh)2 in a constant-pressure calorimeter of negligible heat capacity. the initial temperature of both solutions is the same at 18.46°c. the heat of neutralization when 1.00 mol of hno3 reacts with 0.500 mol ba(oh)2 is −56.2 kj/mol. assume that the densities and specific heats of the solution are the same as for water (1.00 g/ml and 4.184 j/g · °c, respectively). what is the final temperature of the solution?
