How it works
Yield = actual ÷ theoretical × 100
Percent yield compares what you actually obtained to the maximum theoretically possible. Real reactions rarely reach 100% due to losses and side reactions.

Frequently asked questions
Can yield exceed 100%?
Not really — values above 100% usually mean the product is impure or still wet.
What is theoretical yield?
The maximum product predicted by the balanced equation, assuming everything reacts perfectly.
