Computing Molar Mass of Ammonium Hydroxide Step by Step
Molar Mass of Ammonium Hydroxide: Step-by-Step Calculation
1. Identify Element Counts
Read NH4OH and list how many atoms of each element are present:
- 1 atom of Nitrogen (N)
- 5 atoms of Hydrogen (H)
- 1 atom of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Nitrogen (N) ~= 14.007 g/mol
- Hydrogen (H) ~= 1.008 g/mol
- Oxygen (O) ~= 15.999 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Nitrogen (N): 1 x 14.007 = 14.010 g/mol
- Hydrogen (H): 5 x 1.008 = 5.040 g/mol
- Oxygen (O): 1 x 15.999 = 16.000 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (1 x 14.007 + 5 x 1.008 + 1 x 15.999)
Molar Mass = 14.010 + 5.040 + 16.000
Molar Mass = 35.050 g/mol
Final rounded value shown on this page: 35.05 g/mol.

| Element | Count | Mass | Count x mass | Contribution |
|---|---|---|---|---|
| Nitrogen (N) | 1 | 14.007 | 1 x 14.007 | = 14.010 |
| Hydrogen (H) | 5 | 1.008 | 5 x 1.008 | = 5.040 |
| Oxygen (O) | 1 | 15.999 | 1 x 15.999 | = 16.000 |
