Identity summary

Name Barium Chloride
Other names (IUPAC) barium(2+) dichloride
Molecular formula BaCl2
CAS number 10361-37-2
Molar mass 208.23 g/mol
PubChem CID 25204

Molar mass of BaCl2 and how to calculate it

The molar mass of BaCl2 is 208.23 g/mol, the sum of the relative atomic masses of all atoms in the formula: 137.330 + 2 × 35.450 = 208.23 g/mol.

Element Atoms Atomic mass Contribution Mass %
Ba 1 137.330 137.33 65.95%
Cl 2 35.450 70.90 34.05%

So 1 mol of BaCl2 weighs 208.23 g, and 1 L of a 0.1 M solution needs 20.823 g of pure BaCl2. For liquid or concentrated reagents, work from assay and density with the dilution formula. Calculate other compounds with the molar mass calculator.
