The molar mass of CaCl2 is 110.98 g/mol.
A drying agent and road de-icer; dissolving it releases heat.
Step-by-step calculation
Add up the atomic masses of every atom in the formula:
1 × 40.078 + 2 × 35.453 = 110.98 g/mol
| Element | Atoms | Atomic mass (u) | Subtotal (g/mol) | % by mass |
|---|---|---|---|---|
| Calcium (Ca) | 1 | 40.078 | 40.078 | 36.11% |
| Chlorine (Cl) | 2 | 35.453 | 70.906 | 63.89% |
