Answer: hello some part of your question is missing below is the missing part
Using the mass of your "Goody's" powder (1.0g). (Goody's 1g with acetaminophen 260mg; aspirin 520mg; caffeine 32.5mg )
answer:
% aspirin = 52%
%acetaminophen = 26%
% caffeine = 3.25%
The percentages compare favorably with the percent composition claimed by the manufacturer
Step-by-step explanation:
percentage of aspirin
520 mg / 1000 = 0.520 g
0.52/1 * 100 = 52%
percentage of acetaminophen
260 mg / 1000 = 0.26 g
0.26 / 1 * 100 = 26%
percentage of caffeine
32.5 mg / 1000 = 0.0325 g
0.0325 / 1 * 100 = 3.25%
Hence the remaining composition percentage = 100 - ( 52 + 26 + 3.25 )
= 18.75%
The percentages compare favorably with the percent composition claimed by the manufacturer
