One adult aspirin tablet contains 300 milligrams of aspirin.
Not that I know what you mean by a grain but 0.500 g = 500 mg so 500/60=8.34 grains - is this a trick question?
unreacted salicylic acid
It depends on the mass of the tablet and the molar mass of the aspirin molecule itself, find out the mass in grams of one tablet, divide it by the sum of the number of neutrons and protons in one molecule of aspirin and it will give you the molar mass of the aspirin tablet.
aspirin
Givens for question above: If the aspirin tablet is 0.4635g. it was titrated with 18.23mL of 0.1000M NaOH to neutralize. Then 33mL of NaOH was added to hydrolyze. then it was back titrated w/13.59mL HCl. what is mass of acetylsalicylic acid? what is the percent w/w?
aspirin is a popularly known drug. the chemical name of aspirin is acetyl salicylic acid, an organic compound. it is prepared by the reaction of o-hydroxybenzoic acid(salicylic acid) with acetyl chloride or acetic anhydride.
its aspirin - google it and you'll get plenty of structures for it which will be much easier shown in diagram than i can explain. however its basically a benzene ring with a carboxylic acid and an acyl group attached
Can be done two ways. Acidic aqueous solution or Alkali aqueous solution mixed with aspirin and stirred, this breaks the acetyl bond which is present in aspirin.
Aspirin is the trade name for acetylsalicylic acid.
Aspirin is acetylsalicylic acid and an acetate ester of salicylic acid.
