Final answer:
To find the percent yield, calculate the theoretical yield using stoichiometry based on the given reactant masses, then compare it to the actual yield with the formula: Percent Yield = (Actual Yield / Theoretical Yield) × 100%.
Step-by-step explanation:
To determine the percent yield for the reaction, we must first find the theoretical yield and then compare it to the actual yield. Using the given masses of the reactants and possible balanced chemical equation (which is not provided in the question but is necessary for calculation), we can calculate the moles of each reactant, determine the limiting reactant, and use stoichiometry to find the theoretical yield of CS2O. Finally, we use the formula:
Percent Yield = (Actual Yield / Theoretical Yield) × 100%
Given that 28.3 g of CS2O is the actual yield, we can then calculate the theoretical yield with stoichiometry:
(mass of limiting reactant) → (moles of limiting reactant) → (moles of product based on stoichiometry) → (theoretical mass of product)
After calculating the theoretical yield, we substitute it and the actual yield into the percent yield formula. For example, if the theoretical yield calculated was 40.0 g, then the percent yield would be:
Percent Yield = (28.3 g / 40.0 g) × 100% = 70.75%
