What is value of percent atom economy if formula weight of product is 46 u and sum of formula weight of all reactants is 92 u ?

Options

  1. A35 %
  2. B50 %
  3. C40 %
  4. D45 %

Correct answer

B. 50 %

Step-by-step solution

% atom economy = Formula weight of thedesired product Sum of formula weight of all thereactant used in thereaction 100 = 46 92 100=50 %
