WebReactant atoms are wasted for unwanted products. To calculate the atom economy, we can use the following equation: Atom Economy = Mr of the desired productSum of Mr of all products x 100%. Atom economy is 100% for addition reactions since there are no additional products obtained in a reaction rather than the desired one: A + B → AB.
