Calculation for Actual Yield:
Actual Yield = (Mass of filter paper + precipitate + Watch glass) – (Mass of filter paper + Watch glass)
Actual Yield = 48.268 g – 48.027 g
Actual Yield = 0.261 g
Explanation
The actual yield of the precipitate can be determined directly from the experimental data provided on the worksheet. The actual yield is the measured amount of product that is physically recovered from a chemical reaction. To find the mass of just the precipitate, you must subtract the initial mass of the collection apparatus (the filter paper and watch glass) from the final mass of the apparatus with the dried precipitate. The calculation is as follows: 48.268 grams, which is the mass of the filter paper, precipitate, and watch glass, minus 48.027 grams, the mass of just the filter paper and watch glass. This subtraction results in 0.261 grams, which is the actual yield of the precipitate collected in this experiment.
However, it is impossible to calculate the theoretical yield or the percent recovered using only the information given. The theoretical yield is the maximum amount of product that could be formed from the starting materials, calculated using stoichiometry. To perform this calculation, you would need the balanced chemical equation for the reaction and the precise initial amounts, such as mass or molarity, of the reactants used. This information allows you to identify the limiting reactant, which dictates the maximum product quantity. Since the worksheet does not provide details on the reactants or the chemical reaction, the theoretical yield cannot be found.
Consequently, the percent recovered, which is more commonly called the percent yield, also cannot be calculated. The formula for percent yield is (Actual Yield / Theoretical Yield) × 100%. Because the theoretical yield is an unknown value in this context, this final calculation cannot be completed. Therefore, the only result that can be fully determined from the data is the actual yield of 0.261 grams.
