Calculate a high percent yield of 95% when 9.5 g is recovered from a theoretical 10 g.

Frequently asked questions

Can percent yield exceed 100%?
No — a yield above 100% indicates an error such as impure product, incomplete drying, or a mistake in calculating the theoretical yield.
What is a 'good' percent yield?
Depends on the reaction. Industrial processes often target >90%; complex organic syntheses may only achieve 30–50% per step.
