Atom Economy Calculator

Find how efficiently atoms become the desired product.

Atom economy (%) 44

Formula: atom economy = product mass ÷ total reactant mass × 100

Step-by-step with your numbers:

1. Values used:

2. Desired product mass = 44 g/mol

3. Total reactant mass = 100 g/mol

5. Atom economy = (44 / 100) x 100 = 0.44 x 100 = 44%

Did we solve your problem today?

Atom economy measures green-chemistry efficiency — how much reactant mass ends up in the product.

The math behind it

atom economy = mass of desired product ÷ total mass of reactants × 100.

44 of 100 → 44%.

Vs percent yield?

Atom economy is theoretical (from the equation); percent yield is experimental.
