Identification of Acetone Chemical Compound

2D chemical structure image of acetone

Chemical Formula C3H6O
Molecular Weight 58.07914 g/mol
IUPAC Name propan-2-one
InChI InChI=1S/C3H6O/c1-3(2)4/h1-2H3

Molecular Weight Description

The acetone molecule consists of 6 Hydrogen atom(s), 3 Carbon atom(s), and 1 Oxygen atom(s) – a total of 10 atom(s). The molecular weight of acetone is determined by the sum of the atomic weights of each constituent element multiplied by the number of atoms, which is calculated to be:

$$ 58.07914 · \frac{g}{mol} $$

The exact term of the above molecular weight is “molar mass”, which is based on the atomic mass of each element. Molecular weight is actually an older term of “relative molar mass” or “molecular mass”, which is a dimensionless quantity equal to the molar mass divided by the molar mass constant defined by 1 g/mol.
Molecular masses are calculated from the standard atomic weights of each nuclide, while molar masses are calculated from the atomic mass of each element. The atomic mass takes into account the isotopic distribution of the element in a given sample.
