Copper (II) Chloride and iron lab part 2

Today in class we finalized our lab and calculated which iron chloride compound we had in our experiment. By calculating the actual yield of the copper as well as the percent yield of it using both FeCl2 and FeCl3, we could then figure out their percent yields. When we used our numbers we were able to figure out that FeCl3 was used in our experiment because the percent yield of FeCl2 was over 100%.

Here is a link describing the difference between actual and theoretical yield: http://www.science.uwaterloo.ca/~cchieh/cact/c120/yields.html

Here is a picture of our data:
