# What is the molecular weight of aspirin?

Do I need to break down the individual elements?

 +1 vote! +7 you voted Answer by  apsaras (408) Asprin or acetylsalicylic acid has the molecular formula C9H8O4. There are 9 carbon atoms, 8 hydrogen atoms and 4 oxygen atoms in each molecule of asprin. Thus the molecular weight is equal to 9 times 12 plus 8 times 1 plus 4 times 16 which gives a value of 180 grams per mole.

With each carbon atom having a mass of 12.011 amu, each hydrogen having a mass of 1.00794 amu, and each oxygen having a mass of 15.9994 amu, the total mass of aspirin is 180.160 amu or 180.160 g/mol.

To calculate the molecular weight, it is necessary to add the masses of each element from the periodic table : 9(mass of Carbon) + 8(mass of Hydrogen) + 4(mass of Oxygen) = 180.157 g/mol.
