Question

2Fe2O3 + 3C 4Fe + 3C02

You add 28 grams of carbon. You find the actual yield to be 81.2 grams of CO2.
What is the percent yield of CO2 if the theoretical yield is 102.6g?
126.35%
0.79%
1.26%
79.14%

Answer 1

D = 79.14%

Step-by-step explanation:

Actual yield = 81.2g

Theoretical yield = 102.6g

Percentage yield = ?

Percentage yield = (actual yield / theoretical yield) * 100

Percentage yield = (81.2 / 102.6) * 100

Percentage yield = 0.7914 * 100 = 79.14%

Percentage yield of CO2 is 79.14%
