The reactions will be carried out in such a way that the copper metal added in the first
reaction will determine the amount of copper(I) chloride that forms in the last reaction
because it is the limiting reagent in all reactions where it's involved. In other words, all
the other reagents used for this preparation will be added in excess. The theoretical yield
is then based on the amount of copper added in the first reaction.

Expert Answer

Step 1

In chemistry, there are many ways to check the deviation of experimental data from the accurate value. These different methods provide the difference between accuracy and precisions of the experimental data which can be further used to calculate the error percentage in the experiment.

 

Step 2

Given:

 

Cu  =  1.006 g 

Molar mass of Cu  =  63.5 g/mol 

Molar mass of CuCl = 98.99 g/mol  

Step 3

Substitute the values to calculate the theoretical yield:
