Computing Molar Mass of Copper(II) Sulfate Step by Step
Molar Mass of Copper(II) Sulfate: Step-by-Step Calculation
1. Identify Element Counts
Read CuSO4 and list how many atoms of each element are present:
- 1 atom of Copper (Cu)
- 1 atom of Sulfur (S)
- 4 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Copper (Cu) ~= 63.546 g/mol
- Sulfur (S) ~= 32.060 g/mol
- Oxygen (O) ~= 15.999 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Copper (Cu): 1 x 63.546 = 63.550 g/mol
- Sulfur (S): 1 x 32.060 = 32.060 g/mol
- Oxygen (O): 4 x 15.999 = 64.000 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (1 x 63.546 + 1 x 32.060 + 4 x 15.999)
Molar Mass = 63.550 + 32.060 + 64.000
Molar Mass = 159.600 g/mol
Final rounded value shown on this page: 159.60 g/mol.

| Element | Count | Mass | Count x mass | Contribution |
|---|---|---|---|---|
| Copper (Cu) | 1 | 63.546 | 1 x 63.546 | = 63.550 |
| Sulfur (S) | 1 | 32.060 | 1 x 32.060 | = 32.060 |
| Oxygen (O) | 4 | 15.999 | 4 x 15.999 | = 64.000 |
