Atom Economy Calculator

What is Atom Economy?

Atom economy is a concept in green chemistry that measures the efficiency of a chemical reaction in terms of how well atoms are utilized. Higher atom economy indicates a greener, more sustainable process.

How to Use This Calculator

• Enter the mass of the desired product formed in grams.
• Enter the total mass of all reactants used in grams.
• Click on "Calculate" to get the atom economy percentage.

Formula

Atom Economy (%) = (Mass of Desired Product / Total Mass of Reactants) × 100

Example

Suppose you produce 180g of a product from 200g of reactants. Then,
Atom Economy = (180 / 200) × 100 = 90%
