How many moles of c9h8o4 are in a 0.600 g tablet of aspirin?

Aspirin has a chemical name acetylsalicylic acid. It has a chemical formula C9H8O4. So, the problem is just simply asking to convert from units of grams to moles. To do this, we need a factor that would relate the mass and the number of moles. We use the molar mass of the compound. It is the sum of the atomic masses of the atoms in the compound.

molar mass = 9 x C + 8 x H + 4 x O

molar mass = 9 (12.01) + 8 (1.01) + 4 (16.0)

molar mass = 180.17 g / mol

moles C9H8O4 = 0.60 g C9H8O4 (1 mol / 180.17 g)

moles C9H8O4 = 3.33x10^-3 mol
