Computing Molar Mass of Calcium Nitrate Step by Step
Molar Mass of Calcium Nitrate: Step-by-Step Calculation
1. Identify Element Counts
Read Ca(NO3)2 and list how many atoms of each element are present:
- 1 atom of Calcium (Ca)
- 2 atoms of Nitrogen (N)
- 6 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Calcium (Ca) ~= 40.078 g/mol
- Nitrogen (N) ~= 14.007 g/mol
- Oxygen (O) ~= 15.999 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
- Nitrogen (N): 2 x 14.007 = 28.010 g/mol
- Oxygen (O): 6 x 15.999 = 95.990 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 14.007 + 6 x 15.999)
Molar Mass = 40.080 + 28.010 + 95.990
Molar Mass = 164.090 g/mol
Final rounded value shown on this page: 164.09 g/mol.

| Element | Count | Mass | Count x mass | Contribution |
|---|---|---|---|---|
| Calcium (Ca) | 1 | 40.078 | 1 x 40.078 | = 40.080 |
| Nitrogen (N) | 2 | 14.007 | 2 x 14.007 | = 28.010 |
| Oxygen (O) | 6 | 15.999 | 6 x 15.999 | = 95.990 |
