The burning of 18.0 g of carbon produces 55.0 g of carbon dioxide. What is the
theoretical yield of CO2? Calculate the percent yield of CO2.
Write the equation.
Convert 18.0 g C to mols.
Covert mols C to mols CO2 using the coefficients in the balanced equation.
Convert mols CO2 to grams. That will give you the theoretical yield. Then percent yield = [actual amount/theoretical] * 100
Post your work if you get stuck.
