$137$

Vedclass · Answer

(A) The formula for atom economy is defined as: $	ext{Atom Economy} = \left( \frac{	ext{Formula weight of desired product}}{	ext{Sum of formula weights of all reactants}} ight) 	imes 100 \%$Given: $	ext{Sum of formula weights of all reactants} = 274 \ u$$	ext{Atom Economy} = 50 \%$Substituting the values into the formula: $50 = \left( \frac{	ext{Formula weight of desired product}}{274 \ u} ight) 	imes 100$$0.5 = \frac{	ext{Formula weight of desired product}}{274 \ u}$$	ext{Formula weight of desired product} = 0.5 	imes 274 \ u = 137 \ u$Therefore,the correct option is $A$.

In a chemical reaction,the sum of the formula weight of all reactants is $274 \ u$ and the atom economy is $50 \%$. Calculate the formula weight of the desired product. (in $u$)
