What is value of percent atom economy if formula weight of product is \(46 \mathrm{u}\) and sum of formula weight of all reactants is 92 \(\mathrm{u}\) ?
- A \(35 \%\)
- B \(50 \%\)
- C \(40 \%\)
- D \(45 \%\)
Answer & Solution
Correct Answer
(B) \(50 \%\)
Step-by-step Solution
Detailed explanation
\(\%\) atom economy =
\(\frac{\text { Formula weight of thedesired product }}{\text { Sum of formula weight of all thereactant used in thereaction }}\) \(\times 100\)
\(
=\frac{46}{92} \times 100=50 \%
\)
\(\frac{\text { Formula weight of thedesired product }}{\text { Sum of formula weight of all thereactant used in thereaction }}\) \(\times 100\)
\(
=\frac{46}{92} \times 100=50 \%
\)
