To calculate the percent yield of carbon (C), we first need to determine the theoretical yield of carbon dioxide (CO2) and then use it to find the percent yield of carbon.Given information:- Balanced chemical equation:
- Actual yield of CO2: 181.2 grams- Mass of carbon added: 28 gramsStep 1: Calculate the theoretical yield of CO2.Molar mass of CO2 = 44.01 g/molMoles of CO2 = 181.2 g / 44.01 g/mol = 4.13 molTheoretical yield of CO2 = 4.13 mol × 44.01 g/mol = 181.2 gStep 2: Calculate the percent yield of carbon (C).Moles of carbon = 28 g / 12.01 g/mol = 2.33 molTheoretical yield of carbon = 2.33 mol × 12.01 g/mol = 28 gPercent yield of carbon = (Actual yield of carbon / Theoretical yield of carbon) × 100%Percent yield of carbon = (28 g / 28 g) × 100% = 100%Therefore, the correct answer is 100%.
