Extraction Questions

[kimmy]

Hi guys! In class, we did an extraction lab and for the post report, I had 2 questions I had trouble with .

 

1. Prove he conclusion that two extractions of A with 50 mL portions of ether yield 57.8 mg of A, whereas one extraction with 100 mL of ether yields only 53.6 mg of A.

 

2. Calculate the volume of ether needed to remove 90% of the suberic acid from 100 mL of a saturated aqueous solution in a single extraction.

 

 

 

 

Any help would be nice
