A coffee cup calorimeter with a heat capacity of 4.00 J/°C was used to measure the change in enthalpy of a precipitation reaction. A 50.0 mL solution of 0.370 M AgNO, was mixed with 50.0 mL of 0.230 M KBr. After mixing, the temperature was observed to increase by 2.28 °C. Calculate the enthalpy of reaction, AHrxn, per mole of precipitate formed (AgBr). Assume the specific heat of the product solution is 4.10 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 KBr. theoretical moles of precipitate formed from AgNO3: moles
theoretical moles of precipitate formed from KBr: Calculate the heat change experienced by the calorimeter contents, contents- contents = Calculate the heat change experienced by the calorimeter, cal 9cal = Calculate the heat change produced by the solution process, 9solution. solution= moles J J
Calculate the heat change produced by the solution process, solution. solution= Calulate AH solution for one mole of precipitate formed. AH solution = kJ/mole
