Final answer:
The percent yield of the reaction is 30.54%.
Step-by-step explanation:
To calculate the percent yield of a reaction, we use the formula: Percent Yield = (actual yield / theoretical yield) x 100%. In this case, the actual yield is given as 9.95 g of CO2. To find the theoretical yield, we need to calculate the molar quantities of carbon and CO2 using their respective molar masses and the balanced chemical equation. The molar mass of carbon is 12.01 g/mol and the molar mass of CO2 is 44.01 g/mol. From the balanced equation, we see that for every 12.01 g of carbon, we should have 44.01 g of CO2. Therefore, the theoretical yield can be calculated as follows: theoretical yield = (8.90 g carbon) x (44.01 g CO2 / 12.01 g carbon) = 32.56 g CO2. Now we can calculate the percent yield using the formula: Percent Yield = (9.95 g CO2 / 32.56 g CO2) x 100% = 30.54%.
