A styrofoam calorimeter contains 60.0 mL of 0.750 M H3C6H5O7 at 22.8oC. When 9.83 g NaHCO3 is added to the calorimeter, the temperature of the resulting solution decreases to a minimum of 5.1oC. The reaction that occurs is: H3C6H5O7(aq)+3NaHCO3(aq)→Na3C6H5O7(aq)+3CO2(g)+3H2O(l)ΔHreaction=??? What is the (experimental) enthalpy change for this reaction, ΔHreaction? (Use the total mass of solution and 4.18 J/(g oC) for the specific heat of the solution in your calculations.)

Question
A styrofoam calorimeter contains 60.0 mL of 0.750 M H3C6H5O7 at 22.8oC. When 9.83 g NaHCO3 is added to the calorimeter, the temperature of the resulting solution decreases to a minimum of 5.1oC. The reaction that occurs is:
H3C6H5O7(aq)+3NaHCO3(aq)→Na3C6H5O7(aq)+3CO2(g)+3H2O(l)ΔHreaction=???
What is the (experimental) enthalpy change for this reaction, ΔHreaction? (Use the total mass of solution and 4.18 J/(g oC) for the specific heat of the solution in your calculations.)
