A mixture of two compounds, A and B, was separated by extraction. After the compounds were dried, their masses were found to be:

Arlecino [84]

Answer:

The percent recovery from re crystallization for both compounds A and B is 69.745 and 81.44 % respectively.

Explanation:

Mass of compound A in a mixture = 119 mg

Mass of compound A after re-crystallization = 83 mg

Percent recovery from re-crystallization :

$\frac{\text{Mass after re-crystallization}}{\text{Mass before re-crystallization}}\times 100$

Percent recovery of compound A:

$\frac{83 mg}{119 mg}\times 100=69.74\%$

Mass of compound B in a mixture = 97 mg

Mass of compound B after re-crystallization = 79 mg

Percent recovery of compound B:

$\frac{79 mg}{97 mg}\times 100=81.44\%$
