Computing Molar Mass of Silver Nitrite Step by Step
Molar Mass of Silver Nitrite: Step-by-Step Calculation
1. Identify Element Counts
Read AgNO2 and list how many atoms of each element are present:
- 1 atom of Silver (Ag)
- 1 atom of Nitrogen (N)
- 2 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Silver (Ag) ~= 107.868 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:
- Silver (Ag): 1 x 107.868 = 107.870 g/mol
- Nitrogen (N): 1 x 14.007 = 14.010 g/mol
- Oxygen (O): 2 x 15.999 = 32.000 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (1 x 107.868 + 1 x 14.007 + 2 x 15.999)
Molar Mass = 107.870 + 14.010 + 32.000
Molar Mass = 153.870 g/mol
Final rounded value shown on this page: 153.87 g/mol.

| Element | Count | Mass | Count x mass | Contribution |
|---|---|---|---|---|
| Silver (Ag) | 1 | 107.868 | 1 x 107.868 | = 107.870 |
| Nitrogen (N) | 1 | 14.007 | 1 x 14.007 | = 14.010 |
| Oxygen (O) | 2 | 15.999 | 2 x 15.999 | = 32.000 |
