Unformatted text preview: metal was 1.02 J/K g and this made the unknown metal Aluminum. There was a -9.27% error between the calculated and actual atomic mass. In the third part of the experiment we got an experiment value of the change in enthalpy of 2.64X10 4 J/mol and a calculated 2.86X10 4 J/mol. This gave us a -7.69% error. In the fourth part of this experiment we got an experimental value of 364 J/mol and a calculated value of -5.58X10 4 J/mol. Which gave us a 100.7% error. A source of error for this experiment could be that we didn’t measure the right temperatures at given points, which could give us the wrong max temperatures. This would throw off our results completely like in part four of the experiment....
