Calculate the percent atom economy when a product of formula weight \(175 \mathrm{u}\) is obtained in a chemical reaction using \(225 \mathrm{u}\) formula weight reactant.
- A \(70.1 \%\)
- B \(77.7 \%\)
- C \(90.5 \%\)
- D \(95.0 \%\)
Answer & Solution
Correct Answer
(B) \(77.7 \%\)
Step-by-step Solution
Detailed explanation
\(\%\) atom economy
\(=\frac{\text {Formula weight of the desired product}}{\text {Sum of formula weight of all the reactants}}\) \(\times 100\)
\(\text {used in the reaction}\)
\(=\frac{175 \mathrm{u}}{225 \mathrm{u}} \times 100\)
\(=77.7 \%\)
\(=\frac{\text {Formula weight of the desired product}}{\text {Sum of formula weight of all the reactants}}\) \(\times 100\)
\(\text {used in the reaction}\)
\(=\frac{175 \mathrm{u}}{225 \mathrm{u}} \times 100\)
\(=77.7 \%\)
