How to calculate the percent yield of this reaction?

Percent yield calculation: Actual yield (mass of recovered copper) / Theoretical yield (calculated from stoichiometry)

Answers:

Initial mass of copper: 0.614 g

Mass of copper and evaporating dish: 40.042 g

Mass of evaporating dish: 0.602 g

Mass of recovered copper: Unknown (Additional information needed)

Percent yield calculation: Actual yield (mass of recovered copper) / Theoretical yield (calculated from stoichiometry)

To determine the percent yield of the reaction, we need to compare the actual yield (mass of recovered copper) with the theoretical yield calculated from stoichiometry. In this experiment, the initial mass of copper is 0.614 g. The total mass of copper and the evaporating dish is 40.042 g, with the mass of the evaporating dish alone being 0.602 g.

In order to calculate the percent yield accurately, we require the additional information of the mass of the recovered copper. Once we have this data, we can proceed with the calculations by dividing the mass of the recovered copper by the theoretical yield obtained from stoichiometry.
