79.14%
Explanation:
Given the equation : 2Fe2O3 + 3C 4Fe + 3C02
The theoretical yield of CO2 ; is 102.6g
Actual yield = 81.2 gram
Percentage yield = (actual yield / theoretical yield) * 100%
Percentage yield = (81.2 / 102.6) * 100%
Percentage yield = 0.7914230 * 100%
Percentage yield = 79.14%
Hence, tbe percentage yield of CO2 is 79.14%
