# Calcuate % mass of each ingredient

by Rma

(MN)

each capsule of Excedrin migraine contains 250mg of acetaminophen, 250 mg of ASA, 65mg caffeine. If the capsule has an average mass of 0.676g. calculate the percent mass of each active ingredients in a tablet of Excedrin.

I did the math but seems wrong. not sure if this is what the question wants.

I got:

44.2% acetaminophen

44.2% ASA

12% Caffeine

Can you help walk me through?
