Which statement is correct?
Select one:
a. Percentage yield is simply the mass of aspirin isolated divided by the mass of salicylic acid that we started with and converted into a %, i.e. (gaspirin/gsalicylic acid) * 100
b. Percentage yield is simply the mass of aspirin isolated divided by the mass of acetic anhydride that we started with and converted into a %, i.e. (gaspirin/gacetic anhydride) * 100
c. Percentage yield of the aspirin is the moles of aspirin isolated divided by the moles of the reagent and converted into a %, i.e. (molesaspirin/molesreagent) * 100
d. Percentage yield of aspirin is the isolated/actual mass of aspirin isolated divided by the theoretical mass of aspirin, i.e. (gaspirin isolated/gaspirin theoretical) * 100. The theoretical mass of aspirin is calculated based on the moles of the limiting reagent and the stoichiometry of the reaction.
e. Percentage yield of aspirin is the theoretical mass of aspirin isolated divided by the actual/isolated mass of aspirin product, i.e. (gaspirin theoretical/gaspirin isolated) * 100. The theoretical mass of aspirin is calculated based on the moles of the limiting reagent and the stoichiometry of the reaction.
