Report Sheet - Determining Limiting Reactant and Percent Yield Data Mass of empty 150 ml beaker Mass of CuSO4·5H20 Color of Cuso,5%O solution Mass of Al foil pieces 85.3610 2-03( briout biye 0.25 189 parnYoun h_afk Raple Color of Cuso,SHO solution after addition of Al Mass of beaker+ solid copper 35. 8629 Mass of solid copper Data Analysis 1. Balance the reaction conducted in this experiment 2. Calculate the moles of CuSO. 5H:0 used in your experiment. Show your work below 3. Calculate the moles of Al used in the experiment. Show your work below.

Explanation / Answer

Ans 1 :

The balanced reaction is given as :

2Al + 3CuSO4 = 3Cu + Al2(SO4)3

Ans 2 :

The number of moles of CuSO4.5H2O = given mass / molar mass

= 2.0318 / 249.72

= 0.008 moles

Ans 3 :

Number of moles Of Al = 0.25189 / 26.98

= 0.009 moles

Ans 4 :

Number of moles of Cu = number of moles of CuSO4 = 0.008

So theoretical yield of copper = 0.008 x 63.546

= 0.508 grams
