EXPERIMENT #12: Aspirin synthesis
DATA TABLES
Column #2 (video data) in table below is the data obtained by watching the video
Column #3 (student data) is data obtained by a student performing the same reaction. This data will be provided
by your instructor for each student.
Video data
Student data
Weight of Salicylic acid
2.027g
2.110g
Weight of weighing paper
0.354g
0.356g
Weight of weighing paper & Aspirin
2.711g
3.001g
Weight of Aspirin
2.357g
2.645g
RESULTS: Analysis of the experimental data.
138.00
Molecular weight of salicylic acid
Molecular weight of aspirin
180.00
1. Use the values from the DATA table and the molecular weights of salicylic acid and aspirin to determine:
The predicted maximum (theoretical) yield of Aspirin (g).
The experimental yield of Aspirin (g).
The % yield in each experiment
The average % yield for both experiments.
Determine the number of aspirin tablets that could be prepared if a typical tablet contains 325 mg aspirin
(the rest is starch binder and buffer to reduce the possible irritation) in each experiment..
Video data
Student input
The Maximum yield of Aspirin (g)
2.644g
2.752g
The experimental yield of Aspirin (g)
2.357g
2.645g
The % yield in each experiment
89.14g
96.11g
The average % yield
92.63g
Number of tablets that can be prepared 7mg
8mg
Sample calculations:
In the space below show complete calculations for Student Data Include formulas and units.
The Maximum yield of Aspirin (g)
2.110g x 1moleSA/138.00g x 1moleASA/1moleSA x 180.00g/1 moleASA = 2.752g
The experimental yield of Aspirin (g) = Weight of Aspirin
2.645g
The % yield in each experiment
2.645g/2.752g x 100= 96.11g
The average % yield
96.11g+89.14g /2 = 92.63g
Number of tablets that can be prepared
2645mg x 1/325mg = 8mg
