text: The answer is 0.003514 mols acetaminophen.\nHere are the calculations:   \nacet = acetaminophen    tyl=tylenol.\n\n625 mg tyl (85 mg acet/100 mg tyl)*(1 g acet/1000 mg acet)*(1 mol acet/151.17 g acet) = 0.003514 mols acet.\n\nThe whole calculation can be done in one line of math using stoichiometry.
