Percent Yield: 8 g Actual vs 10 g Theoretical
Obtaining 8 g of product when 10 g is expected gives a percent yield of 80%.

Find the percent yield for a reaction producing 8 g of product with 10 g theoretical yield.
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.
