Actual Yield
The mass of pure product actually isolated at the end of an experiment.
Unit
g
In depth
Actual yield is measured after the product has been separated, purified and dried, so it always falls short of the theoretical value. Common losses include incomplete reaction, competing side reactions, material left on glassware, and product remaining dissolved in the mother liquor after crystallisation.
Examples in the real world
Recovering 4.6 g of calcium oxide where 5.6 g was theoretically possible.
