Question
When 130. mL of 0.204 M NaCl(aq) and 130. mL of 0.204 M AgNO3(aq), both at 21.1°C, are mixed in a coffee cup calorimeter, the temperature of the mixture increases to 23.6°C as solid AgCl forms.
NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq)
This precipitation reaction produces 2.71x10³ J of heat, assuming no heat is absorbed by the calorimeter, no heat is exchanged between the calorimeter and its surroundings, and that the specific heat and density of the solutions are the same as those for water
(4.18 J/g.°C, and 0.997 g/mL, respectively). Using this data, calculate AH in kJ/mol of AgNO3(aq) for the given reaction.
