Jon Almen Introduction We are extracting the active ingredient
Diphenhydramine Hydrochloride
from the following medications: Equate Benadryl Liquid Gels Benadryl Pill = 240 mg
Active ingredient = 16.7mg

Active ingredient per pill
is 6.95% of the total mass.

percent error 33%
Pill = 226 mg
Active ingredient = 15.2 mg

Active ingredient per pill
is 6.74% of the total mass.

percent error 39% Pill = 418 mg
Active ingredient = 14.3 mg

Active ingredient per pill
is 3.42% of the total mass. 500 mg 250 mg Equate
240mg Benadryl
226mg Liquid Gels
418mg Mass of the
individual pill 20 mg 10 mg Equate

3.42%
of the total mass of 418mg What could have effected the ending mass of
Diphenhydramine Hydrochloride ? How many times do you need to extract with Ether to get a more exact result? Ether is lighter than water and floats to the top making it easy to pour off the top.
