Computing Molar Mass of Nickel(II) Hydroxide Step by Step
Molar Mass of Nickel(II) Hydroxide: Step-by-Step Calculation
1. Identify Element Counts
Read Ni(OH)2 and list how many atoms of each element are present:
- 1 atom of Nickel (Ni)
- 2 atoms of Oxygen (O)
- 2 atoms of Hydrogen (H)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Nickel (Ni) ~= 58.693 g/mol
- Oxygen (O) ~= 15.999 g/mol
- Hydrogen (H) ~= 1.008 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Nickel (Ni): 1 x 58.693 = 58.690 g/mol
- Oxygen (O): 2 x 15.999 = 32.000 g/mol
- Hydrogen (H): 2 x 1.008 = 2.020 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (1 x 58.693 + 2 x 15.999 + 2 x 1.008)
Molar Mass = 58.690 + 32.000 + 2.020
Molar Mass = 92.710 g/mol
Final rounded value shown on this page: 92.71 g/mol.

| Element | Count | Mass | Count x mass | Contribution |
|---|---|---|---|---|
| Nickel (Ni) | 1 | 58.693 | 1 x 58.693 | = 58.690 |
| Oxygen (O) | 2 | 15.999 | 2 x 15.999 | = 32.000 |
| Hydrogen (H) | 2 | 1.008 | 2 x 1.008 | = 2.020 |
