What is the percentage atom economy when formula weight of product is 65 u and the sum of formula weight of reactant is 130 u?

Options

A65 %
B70 %
C40 %
D50 %

Correct answer

D. 50 %

Step-by-step solution

The percentage atom economy is calculated using the formula: Percentage atom economy = Formula weight of desired product Sum of formula weights of all reactants 100 Substituting the given values: Percentage atom economy = 65 130 100 = 50 % Answer: 50 %
