Using the information from number one, calculate the empirical and molecular formula for the scenario and then the chemical compound.
Transcribed Image Text:ur possible causes of his untimely death have been suggested by his wife who has
en ruled out as a suspect because of an air-tight alibi.
ur task is to identify who and what killed Tony Smith.
1. An unlabeled drug bottle was found in the medicine cabinet of Smith's bathroom.
A 100 g sample of the drug was analyzed and found to contain 64.94% C, 4.50
% H, 20.36% O, and 10.20% S. The molar mass of the compound was found to
be 314.38 g/mol. It may be a drug prescribed for osteoarthritis. Coincidentally,
Smith's arthritis has become so intolerable in recent weeks that he's had to rely
on the aid of a crutch for mobility. Prolonged ingestion of this drug is thought to
lead to a heart attack. Smith's doctor, Franklin Finch, has a quiet reputation of
prescribing dangerous drugs to "dispose of" unwanted patients. Lately, Smith
has been gaining more recognition in the community due to his latest research
on aromatic hydrocarbons. Could Finch's jealousy by the cause of Tony Smith's
death?
2. Several of Smith's full or partial fingerprints were retrieved from a tipped cup
found near the crime scene. A faint almond scent was detected around the rim.
An 823.15 g liquid sample of the compound was found to contain 3.74% H,
44.43% C, and 51.83% N. The molar mass was determined to be 27.03 g/mol.
A friend of Smith's noticed a disgruntled neighbor, Sheldon Lemieux,
uncharacteristically eager to provide refills. Could this be the answer?
