A student titrating a sample of a powdered aspirin tablet to
find out how much acetylsalicylic acid is in the sample finds that
it requires 30.5 mL of a 0.0907M sodium hydroxide solution to

and explain how you got it. I am not sure I am doing this
right.
SYNTHESIS OF ASPIRIN
Procedure:
Start heating a water bath in your 250 mL beaker by filling it
with ~150 mL of tap water.
Carefully weigh out 1.0 gram of salicylic acid. Transfer to a 50
mL Erlenmeyer flask.
In the fume hood,...
