MSDS Sodium Carbonate (Na2CO3) – Safety Data Sheet & GHS Hazards

Summary MSDS for Sodium Carbonate (Na2CO3), CAS 497-19-8: substance identity, GHS hazard classification, hazard and precautionary statements, and links to the manufacturer's official SDS.

Identity summary

Name	Sodium Carbonate
Other names (IUPAC)	disodium;carbonate
Molecular formula	Na2CO3
CAS number	497-19-8
Molar mass	105.988 g/mol
PubChem CID	10340

Molar mass of Na2CO3 and how to calculate it

The molar mass of Na2CO3 is 105.99 g/mol, the sum of the relative atomic masses of all atoms in the formula: 2 × 22.990 + 12.011 + 3 × 15.999 = 105.99 g/mol.

Element	Atoms	Atomic mass	Contribution	Mass %
Na	2	22.990	45.98	43.38%
C	1	12.011	12.01	11.33%
O	3	15.999	48.00	45.29%

So 1 mol of Na2CO3 weighs 105.99 g, and 1 L of a 0.1 M solution needs 10.599 g of pure Na2CO3. For liquid or concentrated reagents, work from assay and density with the dilution formula. Calculate other compounds with the molar mass calculator.

What is an MSDS/SDS?

An MSDS (Material Safety Data Sheet), now called an SDS (Safety Data Sheet), is a 16-section document describing the hazards, handling, storage, first aid, and disposal of a chemical. Read the full MSDS guide and other MSDS pages.
