Concept:In stoichiometry, there is a distinct difference between the mathematically predicted mass of a product and the physical mass collected after a real-world experiment.
Formula:$$ \text{Actual Yield} < \text{Theoretical Yield} $$
Solution:- The amount of product obtained practically through an experiment is, by definition, the Actual Yield (also known as the experimental yield).
- It is almost always less than the theoretical yield due to mechanical losses, side reactions, and incomplete conversions.
Why other options are incorrect:- Theoretical yield: The maximum possible amount calculated strictly on paper using stoichiometry.
- Percent yield: A ratio comparing actual yield to theoretical yield, not the physical amount itself.
- Mole: A unit of measurement, not a classification of reaction efficiency.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
