Identity summary

Name Acetic Acid
Other names (IUPAC) –
Molecular formula CH3COOH
CAS number 64-19-7
Molar mass 60.05 g/mol
PubChem CID 176

Molar mass of CH3COOH and how to calculate it

The molar mass of CH3COOH is 60.05 g/mol, the sum of the relative atomic masses of all atoms in the formula: 2 × 12.011 + 4 × 1.008 + 2 × 15.999 = 60.05 g/mol.

Element Atoms Atomic mass Contribution Mass %
C 2 12.011 24.02 40.00%
H 4 1.008 4.03 6.71%
O 2 15.999 32.00 53.28%

So 1 mol of CH3COOH weighs 60.05 g, and 1 L of a 0.1 M solution needs 6.005 g of pure CH3COOH. For liquid or concentrated reagents, work from assay and density with the dilution formula. Calculate other compounds with the molar mass calculator.
