Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%
An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients
a.
Reaction
Fe₂O₃+3CO⇒2Fe+3CO₂
MW Fe₂O₃ : 159.69 g/mol
mol Fe₂O₃
![\tt \dfrac{100}{159,69}=0.626](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B100%7D%7B159%2C69%7D%3D0.626)
mol Fe₂O₃ : mol Fe = 1 : 2
mol Fe :
![\tt \dfrac{2}{1}\times 0.626=1.252](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B2%7D%7B1%7D%5Ctimes%200.626%3D1.252)
mass of Fe(Ar=55.845 g/mol) :
![\tt 1.252\times 55.845=69.92~g](https://tex.z-dn.net/?f=%5Ctt%201.252%5Ctimes%2055.845%3D69.92~g)
b.
actual yield = 65 g
theoretical yield = 69.92 g
percent yield :
![\tt =\dfrac{65}{69.92}=0.93=93\%](https://tex.z-dn.net/?f=%5Ctt%20%3D%5Cdfrac%7B65%7D%7B69.92%7D%3D0.93%3D93%5C%25)
