Theoretical Yield Calculator

Calculate the theoretical yield of a product from the limiting reactant.

Introduction

Theoretical Yield Calculator — Calculate the theoretical yield of a product from the limiting reactant. Enter Moles of limiting reactant, Coefficient of limiting reactant, Coefficient of product, Molar mass of product (g/mol) to get an instant, accurate result.

Formula

Theoretical yield (g) = moles of limiting reactant × (coefficient of product / coefficient of limiting reactant) × molar mass of product.

Step-by-step

  1. Enter the Moles of limiting reactant.
  2. Enter the Coefficient of limiting reactant.
  3. Enter the Coefficient of product.
  4. Enter the Molar mass of product (g/mol).
  5. Click Calculate to see your result instantly.

Real-world example

Example: With Moles of limiting reactant = 2, Coefficient of limiting reactant = 2, Coefficient of product = 1, Molar mass of product (g/mol) = 18.015, the Theoretical Yield Calculator gives Theoretical Yield G: 18.015.

Frequently Asked Questions

Why is the calculation based on the limiting reactant?
The limiting reactant runs out first and determines the maximum amount of product the reaction can possibly form, regardless of how much excess reactant remains.
How does this relate to percent yield?
Percent yield = (actual yield / theoretical yield) × 100 — this calculator provides the theoretical yield denominator for that comparison.
What inputs does the Theoretical Yield Calculator need?
You'll need to provide: Moles of limiting reactant, Coefficient of limiting reactant, Coefficient of product, Molar mass of product (g/mol). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Theoretical Yield Calculator?
The Theoretical Yield Calculator applies the formula exactly as calculated — Theoretical yield (g) = moles of limiting reactant × (coefficient of product / coefficient of limiting reactant) × molar mass of product. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Theoretical Yield Calculator free to use?
Yes, the Theoretical Yield Calculator is completely free, requires no signup, and runs instantly in your browser.

About the Theoretical Yield Calculator

The Theoretical Yield Calculator uses a real, verifiable formula — Theoretical yield (g) = moles of limiting reactant × (coefficient of product / coefficient of limiting reactant) × molar mass of product. — so results are accurate every time, not an approximation.
