Iron is extracted from iron oxide in the Blast Furnace: Fe 2 O 3 + 3 CO → 2 Fe + 3 CO 2 a) Calculate the maximum theoretical mass of iron that can be made from 100g
of iron oxide.
b) In the reaction, only 65 g of iron was made. Calculate the percentage yield.

a. mass of iron = 69.92 g

b. percent yield = 93%

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
