For the balanced equation: 2Al(s) +3CuCl2(aq) → 2AlCl3(aq) + 3Cu(s) The reaction consumes 8.25 grams of Al and produces 27.5g Cu(s) in the lab. a) What is the theoretical yield of copper? b) what is the percent yield?

can you attach a picture of the lettuce? : )

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

thats how its supposed to be
