Answer:

The percentage of mass recover from recrystallization = 24.69 %

Explanation:

Given that

Initial mass of crude acetanilide = 166 gm

The mass after recrystallization = 125 gm

The mass recover from recrystallization= 166 - 125 gm

The mass recover from recrystallization= 41 gm

The percentage of mass recover from recrystallization can be find as

$percentage\ of\ mass\ recover\ from\ recrystallization\ =\dfrac{166-125}{166}$

The percentage of mass recover from recrystallization = 24.69 %
