The formula for atom economy is given by:

$\%\text{ Atom economy}=\frac{\text{Formula weight of desired product}}{\text{Sum of formula weights of all reactants}}\times 100$

Substituting the given values into the formula:

$50=\frac{\text{Formula weight of desired product}}{274}\times 100$

$\text{Formula weight of desired product}=\frac{50\times 274}{100}$

$\text{Formula weight of desired product}=137\text{ u}$

Answer: 137 u
