Question

Atom economy is Atom economy is counting the atoms in the starting material and product. the calculation of the number of atoms conserved in the desired product rather than in waste. having green by-products. having green starting materials.

Answer 1

Answer:  the calculation of the number of atoms conserved in the desired product rather than in waste.

Explanation:

Atom economy gives how much desired product is obtained compared to amount of starting materials.

$\text {Atom economy}=\frac{\text {molecular weight of desired product}}{\text {molecular weight of all products}}\times 100%$

For example:

$CH_4+2O_2\rightarrow CO_2+2H_2O$

$\text {atom economy of water}=\frac{\text {molecular weight of desired product}}{\text {molecular weight of all products}}\times 100%$

$\text {atom economy of water}=\frac{36}{44+36}\times 100%=45\%$

Thus atom economy for water is 45%
