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:

a graduated cylinder.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
