The mass (in grams) of copper produced is 2.46 g .
*The limiting reagent is Iron (steel wool)
1)Calculate the theoretical yield (in grams) of Copper?
a) 3.99
b) 1.28
c) 2.28
d) 1.98
2)What is the actual yield of Copper?
a) 2.78
b) 3.99
c) 2.58
d) 2.46
3)Determine the percent yield.
a) 61%
b) 67%
c) 88%
d) 108%
4) What type of reaction occurred
Solution:
NB!!!: insufficient data to complete answer these questions!!!
Most likely, the mass (or the moles) of the limiting reagent (iron) is not provided
copper(II) sulphate + iron metal = copper + iron(II) sulphate
Balanced chemical equation:
CuSO4(aq) + Fe(s) → Cu(s) + FeSO4(aq)
According to stoichiometry: 1 mol of Fe produces 1 mol of Cu
(2) What is the actual yield of copper? - Answer (2): d) 2.46
(3) Determine the percent yield.
Percent yield = (Actual yield of copper / Theoretical yield of copper) × 100%
(4) What type of reaction occurred. - Answer (4): Single-replacement reaction
