| Name | Methanol |
|---|---|
| Other names (IUPAC) | – |
| Molecular formula | CH3OH |
| CAS number | 67-56-1 |
| Molar mass | 32.042 g/mol |
| PubChem CID | 887 |
Molar mass of CH3OH and how to calculate it
The molar mass of CH3OH is 32.04 g/mol, the sum of the relative atomic masses of all atoms in the formula: 12.011 + 4 × 1.008 + 15.999 = 32.04 g/mol.
| Element | Atoms | Atomic mass | Contribution | Mass % |
|---|---|---|---|---|
| C | 1 | 12.011 | 12.01 | 37.49% |
| H | 4 | 1.008 | 4.03 | 12.58% |
| O | 1 | 15.999 | 16.00 | 49.93% |
So 1 mol of CH3OH weighs 32.04 g, and 1 L of a 0.1 M solution needs 3.204 g of pure CH3OH. For liquid or concentrated reagents, work from assay and density with the dilution formula. Calculate other compounds with the molar mass calculator.
