G150 ml of a 0.776 m hcl aqueous solution is mixed with 150 ml of 0.388 m ba(oh)2 aqueous solution in a coffee-cup calorimeter. both the solutions have an initial temperature of 33.8°c. calculate the final temperature of the resulting solution, given the following information: h+(aq) + oh- (aq) → h2o(ℓ) δhrxn = -56.2 kj/mol assume that volumes can be added, that the density of the solution is the same as that of water (1.00 g/ml), and the specific heat of the solution is the same as that for pure water, 4.184 j/(gk).
