What is the percentage atom economy when formula weight of product obtained is 70 u and the sum of formula weight of reactant is 140 u ?
- A \(30 \%\)
- B \(35 \%\)
- C \(50 \%\)
- D \(75 \%\)
Answer & Solution
Correct Answer
(C) \(50 \%\)
Step-by-step Solution
Detailed explanation
\(\% \text { atom economy}\)
\(=\frac{\text {Formula weight of the desired product}}{\text {Sum of formula weight of all the}}\) \(\times 100\)
\(\text {reactants used in the reaction}\)
\(=\frac{70 \mathrm{u}}{140 \mathrm{u}} \times 100=50 \%\)
\(=\frac{\text {Formula weight of the desired product}}{\text {Sum of formula weight of all the}}\) \(\times 100\)
\(\text {reactants used in the reaction}\)
\(=\frac{70 \mathrm{u}}{140 \mathrm{u}} \times 100=50 \%\)
