Computing Molar Mass of Calcium Chloride Step by Step
Molar Mass of Calcium Chloride: Step-by-Step Calculation
1. Identify Element Counts
Read CaCl2 and list how many atoms of each element are present:
- 1 atom of Calcium (Ca)
- 2 atoms of Chlorine (Cl)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Calcium (Ca) ~= 40.078 g/mol
- Chlorine (Cl) ~= 35.450 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Calcium (Ca): 1 x 40.078 = 40.080 g/mol
- Chlorine (Cl): 2 x 35.450 = 70.900 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (1 x 40.078 + 2 x 35.450)
Molar Mass = 40.080 + 70.900
Molar Mass = 110.980 g/mol
Final rounded value shown on this page: 110.98 g/mol.

| Element | Count | Mass | Count x mass | Contribution |
|---|---|---|---|---|
| Calcium (Ca) | 1 | 40.078 | 1 x 40.078 | = 40.080 |
| Chlorine (Cl) | 2 | 35.450 | 2 x 35.450 | = 70.900 |
Final molar mass 40.080 + 70.900 | = 110.980 | |||
