Our Theoretical Yield Calculator simplifies complex stoichiometric calculations. It provides accurate results. Whether you’re a student learning the basics of chemistry or a researcher planning experiments. This calculator provides the reliability and ease of use you need.
Theoretical yield represents the perfect scenario. Use it as a benchmark to evaluate your actual experimental results and improve your chemistry techniques.
Our calculator uses the fundamental theoretical yield formula:
Theoretical Yield = (Moles of Limiting Reagent) × (Molecular Weight of Product) × (Stoichiometric Ratio)
Step 1: Identify Your Limiting Reagent
The limiting reagent runs out first in your reaction. It controls how much product you can make.
How to find it:
Step 2: Enter Limiting Reagent Data
Step 3: Enter Product Information
Step 4: Calculate and Analyze
Hit the “Calculate” button and get your theoretical yield in grams.
Stoichiometry tells us the exact ratio of reactants to products. Here’s how it works:
Example Reaction: 2H₂ + O₂ → 2H₂O
This means 2 molecules of hydrogen react with 1 molecule of oxygen to make 2 molecules of water.
Let’s calculate theoretical yield for making water:
Given:
Using our calculator:
Limiting Reagent (H₂):
Product (H₂O):
Result: Theoretical yield = 36g of water
There’s only one limiting reagent per reaction. Recalculate to find which one truly limits the reaction.
Results are mathematically accurate based on your inputs. Real-world yields will be lower due to practical limitations.
Enter mass in grams and molecular weights in g/mol for best results.
