**Theoretical and Actual Yield Calculation of Copper (Cu)** **Theoretical Yield of Cu in Moles:** - Calculated to be 0.078 moles. - Calculation: \( 0.052 \, \text{moles} \times \frac{3}{2} = 0.078 \, \text{moles} \). **Theoretical Yield of Cu in Grams:** - Calculated to be 4.95 grams. - Calculation: \( 0.078 \, \text{mol} \times 63.5 \, \text{g/mol} = 4.95 \, \text{grams} \). **Actual Yield of Cu in Grams:** - Measured to be 3.06 grams. - Calculation: \( 5.46 \, \text{g} - 2.40 \, \text{g} = 3.06 \, \text{g} \). **Percent Yield of Cu:** - Calculated to be 162%. - Calculation: \( \left(\frac{4.95 \, \text{g}}{3.06 \, \text{g}}\right) \times 100 = 162\% \). These calculations are essential in understanding the efficiency of chemical reactions, with the percent yield indicating how close the actual yield is to the theoretical prediction.
