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
[tex]percentage\ of\ mass\ recover\ from\ recrystallization\ =\dfrac{166-125}{166}[/tex]
The percentage of mass recover from recrystallization = 24.69 %
In the given question, the percent recovery from recrystallization is 75.3 percent.
What is percent recovery?
It is the term generally used in organic chemistry regarding the process of recrystallization. It is the concentration of the pure compound with respect to the impure compound attained from the synthesis of chemical.
Based on the given information:
- The initial mass of the crude acetanilide was 166 mg.
- The mass after recrystallization was 125 mg.
The formula to calculate percent recovery is,
Percent recovery = Amount of product collected post recrystallization/Initial amount of product × 100
Now putting the values we get,
[tex]Percent recovery = \frac{125}{166} * 100\\Percent recovery = 75.3 percent[/tex]
Thus, the percent recovery after recrystallization is 75.3 percent.
