Identity summary

Name Calcium Chloride
Other names (IUPAC) calcium dichloride
Molecular formula CaCl2
CAS number 10043-52-4
Molar mass 110.98 g/mol
PubChem CID 5284359

Molar mass of CaCl2 and how to calculate it

The molar mass of CaCl2 is 110.98 g/mol, the sum of the relative atomic masses of all atoms in the formula: 40.078 + 2 × 35.450 = 110.98 g/mol.

Element Atoms Atomic mass Contribution Mass %
Ca 1 40.078 40.08 36.11%
Cl 2 35.450 70.90 63.89%

So 1 mol of CaCl2 weighs 110.98 g, and 1 L of a 0.1 M solution needs 11.098 g of pure CaCl2. For liquid or concentrated reagents, work from assay and density with the dilution formula. Calculate other compounds with the molar mass calculator.
