You place 40.6 ml of 0.659 m naoh in a coffee- cup calorimeter at 25.00°c and add 71.3 ml of 0.659 m hcl, also at 25.00°c. after stirring, the final temperature is 28.57°c. [assume the total volume is the sum of the individual volumes and that the final solution has the same density (1.00 g/ml) and specific heat capacity (4.184 j/gk)]. calculate the change in enthalpy (latex: \deltaδh) of the reaction in kj/mol of water formed. enter to 1 decimal place.
