Answer to Question #123146 in Inorganic Chemistry for Sakhile

Question

Determine the mass in grams of carbon in a pain tablet that contains 320 mg of aspirin

Answer 1

M(C₉H₈O₄) = 180.15 g/mol

M(C₉) = 108.09 g/mol

Proportion 1:

180. 15 – 100 %

108.09 – x %

x = 60 % - content of carbon in aspirin

Proportion 2:

320 mg – 100 %

y – 60 %

y = 192 mg - mass of carbon in a pain tablet that contains 320 mg of aspirin

Answer: 192 mg
