A coffee cup calorimeter with a heat capacity of 5.80 J/∘ C was used to measure the change in enthalpy of a precipitation reaction. A 50.0 mL solution of 0.360 M AgNO3 was mixed with 50.0 mL of 0.460 M KI. After mixing, the temperature was observed to increase by 4.71∘C. Calculate the enthalpy of reaction, Δrxn, per mole of precipitate formed (AgI). Assume the specific heat of the product solution is 4.18 J / (g⋅∘C) and that the density of both the reactant solutions is 1.00 g/mL.

Calculate the theoretical moles of precipitate formed from AgNO3 and KI.
