calculate the percent aspirin acetaminophen caffeine you isoated from your sample of goody's analgesic powder. does this compare favorably with the percent composition claimed by the manufactuer

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 )

% aspirin = 52%

%acetaminophen = 26%

% caffeine = 3.25%

The percentages compare favorably with the percent composition claimed by the manufacturer

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
