Question

I need help calculating total percent recovery. I have to get the percent recovery for the two compounds I separated during an organic base and neutral compound extraction experiment. The lab started with 0.6 g of a 1:1 mixture (by mass) of 1,4-dichlorobenzene/ethyl 4-aminobenzoate.

My two compounds are 1) 1,4-dichlorobenzene in 95% ethanol and 2) ethyl 4-aminobenzoate in hot 95% ethanol.

These are my results:

1,4-dichlorobenzene recovered 0.329 g

ethyl 4-aminobenzoate recovered 0.271 g

Please show all work on how to find the percent recovery of each compound.

Answer 1

Percent Recovery=- 100 Amount of substance you overy = - actually collected x Amount of substance you were supposed to collect Here The The start with, amount of " " 1,4-dichlomo benezene = 0.6 g 4-aminobenzoate =0.6 g The amount recovered, 1,4 - dichlorobenzene = 0.329 g 4-aminobenzoate = 0.271 g The Percent becovery of 1,4-diehlonobenzene 30062x100 = 540834% 754.837) The Percent becovery of 4-aminobenzoate, - 0.2711 -0.24x100 7345-17%
