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:

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

Greater than ___________ mcg/dl is considered a high level of morning cortisol.

Natalija [7]

Greater than 23mcg/dl is considered a high level of morning cortisol.

Normally, cortisol levels rise during the early morning hours and are highest about 7AM. They drop very low in the evening and during the early phase of sleep. If you do not have this daily change (diurnal rhythm) in cortisol levels, you may have overactive adrenal glands. This condition is called Cushing's syndrome.
