Experiment 4: Separation of a Carboxylic Acid, an Amine, and a Neutral Compound Lab Report
You may write the following answers neatly in pencil or pen. You must think about significant figures in
all of your numbers! You must show all of your work (with units).
Part 1: NUMBERS
1. Data from the experiment:
Mass of original mixture you started with
2009
grams
Mass of Benzoic Acid isolated
Mass of empty flask
2720% grams
Mass of flask + benzoic acid
grams
Mass of benzoic acid
grams
Mass of Biphenyl isolated
Mass of empty flask
146, 813
grams
Mass of flask + biphenyl
grams
Mass of biphenyl
grams
Mass of Ethyl 4-aminobenzoate isolated
Mass of empty flask
grams
Mass of flask + aminobenzoate
grams
Mass of aminobenzoate
grams
2. Total mass of all three compounds isolated
grams
MR. what is the ratio of Benzoic Acid to Biphenyl to Ethyl 4-aminobenzoate in the starting mixture'?
week
To answer this question, set the lowest amount to 1 - i.e. divide all of the masses by the lowest
mass. Do NOT round your numbers; even the 1 should be to the correct number of significant
figures.
Benzoic Acid
Biphenyl
Aminobenzoate
