Amixture of two compounds, a and b, was separated by extraction. after the compounds were dried, their masses were found to be: 119 mg of compound a and 97 mg of compound b. both compounds were recrystallized and weighed again. after recrystallization, the mass of compound a was 83 mg and the mass of compound b was 79 mg. calculate the percent recovery from recrystallization for both compounds.

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 :

Percent recovery of compound A:

Mass of compound B in a mixture  = 97 mg

Mass of compound B after re-crystallization = 79 mg

Percent recovery of compound B:
