Purpose : The purpose of this lab is to develop an understanding of temperature, heat, heat capacity, and specific heat. Calorimetry will be used to determine the specific heat of an unknown metal and to measure the heat of solution of an ammonium salt. Procedure : Pages 24-25 Data : See Attached Calculations : Summary of Results : Specific Heat of Metal : Calorimeter # 14 Unknown # Specific Heat of Metal .313 J/ o C*g Specific Heat of Solution : Calorimeter # : 14 Identity of Salt : Ammonium Nitrate Experimental Δ H solution (kJ/mol): Trial 1: 18.05 Trial 2: 17.71

Unformatted text preview: Average Δ H solution (kJ/mol): 17.88 Theoretical Δ H solution (kJ/mol): Conclusion : The purpose of this lab was to determine the specific heat of an unknown metal and also of a salt solution. We accomplished this task by the method of calorimetry and using the change in temperate and volume to determine the specific heat of both. One source of error could be in measurements that were taken. Also some of the salt fell off the weighing paper while we were weighing the salt. Lastly there is a chance we did not wait long enough for the temperature to level off while taking the measurements with the computer....
