Percent Yield Calculator
The Percent Yield Calculator helps you calculate the efficiency of a chemical reaction by comparing the actual yield to the theoretical yield. It is widely used in chemistry to measure the productivity of reactions.
Formula
Percent Yield = (Actual Yield / Theoretical Yield) * 100

FAQs
What is percent yield?
Percent yield is a measure of the efficiency of a chemical reaction. It compares the actual yield obtained from the reaction to the theoretical yield calculated based on stoichiometry.
Why is percent yield important?
Percent yield helps chemists understand the effectiveness of a reaction and identify potential losses or inefficiencies during the process.
What causes low percent yield?
Low percent yield can result from incomplete reactions, side reactions, measurement errors, or losses during product isolation and purification.
What is a good percent yield?
A good percent yield varies depending on the reaction. Generally, yields above 90% are excellent, while yields around 50% are moderate.
How do I calculate percent yield manually?
Divide the actual yield by the theoretical yield, multiply by 100, and express the result as a percentage.
Can percent yield be over 100%?
Yes, percent yield can exceed 100% if there are measurement errors or impurities in the product.
Is percent yield always accurate?
No, percent yield depends on accurate measurements and proper experimental conditions. Errors can affect its accuracy.
How does temperature affect percent yield?
Temperature can influence reaction rates and equilibrium, affecting the actual yield and hence the percent yield.
How is percent yield used in industries?
Industries use percent yield to optimize production processes, reduce waste, and maximize efficiency.
What units are used in percent yield?
Percent yield is a unitless quantity expressed as a percentage of actual yield to theoretical yield.
