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...

You will apply what you have learned earlier in the semester when performing the Acid-Base Extraction experiment to perform a different separation: that of an organic neutral compound and organic base. You will also need to purify and characterize these compounds. You will have one lab period to execute your plan for separating the assigned mixture given below. There will be a 1:1 (by mass) mixture placed in the lab: 1,4-dichlorobenzene/ethyl 4-aminobenzoate. You will take approximately 1 g of your...

I need help with a buffer equation. I am having a hard time
answering the three questions on here.
The pH is 7.40 and the concentration in M is 0.100. the total
volume in mL is 100.00. The pKa of H2PO4- is 7.21. The conjugate
acid and base to make the phosphate buffer are H2PO4- and
HPO4^2-
Equation (3) in the lab manual is pH = pKa + log (molesB /
molesA).
Equation (1) is [buffer] = Stot / L...
