    An aspirin tablet contains 325 mg acetylsalicylic acid. How many acetylsalicylic acid molecules does it contain?

    The formula of acetylsalicylic acid is C9H8O4. And the gram formula mass of the molecule is 180 g/mol. So there is 325/180=1,8 mol. There is 6,02*10^23 molecules per mol. So the answer is 1,08*10^24 molecules.
