Percent Yield vs Actual Yield
公式
## How to Calculate Percent Yield ### Formula **% Yield = (actual yield / theoretical yield) × 100**
计算示例
A reaction produces 18.5 g but the theoretical yield is 22 g.
- 01% Yield = (18.5 / 22) × 100
- 02% Yield = 84.09%
常见问题
Can percent yield exceed 100%?
In theory no, but impure products or measurement errors can give apparent yields above 100%.
What is a good percent yield?
It depends on the reaction. Many organic syntheses consider 60-80% good, while industrial processes aim for 90%+.
Why is percent yield important?
It measures reaction efficiency, helps optimize conditions, and is essential for cost analysis in manufacturing.
