Final answer:
The formula to calculate theoretical atom economy is (molar mass of desired product / molar mass of all reactants) x 100. Atom economy is a measure of the efficiency of a chemical reaction, indicating the proportion of atoms in the reactants that end up in the desired product.
Step-by-step explanation:
The formula to calculate theoretical atom economy is:
Atom economy = (molar mass of desired product / molar mass of all reactants) x 100
Atom economy is a measure of the efficiency of a chemical reaction, indicating the proportion of atoms in the reactants that end up in the desired product. It is calculated by comparing the molar mass of the desired product to the sum of the molar masses of all the reactants, and then multiplying by 100 to express the result as a percentage.
