Molar Mass Calculator
What is the molar mass of CuSO4?
Answer
M(CuSO4) ≈
159.60 g/mol
Atomic weights: IUPAC standard values (CIAAW, 2024); the sum is rounded to the decimal places of the least precise one — S: 32.06.
| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Cucopper | 1 | 63.546 | 63.546 w ≈ 39.82% | ≈ 39.82% |
| Ssulfur | 1 | 32.06 | 32.06 w ≈ 20.09% | ≈ 20.09% |
| Ooxygen | 4 | 15.999 | 63.996 w ≈ 40.10% | ≈ 40.10% |
| Σ = 159.602 ≈ 159.60 g/mol w = 100% | 100% | |||
Each fraction is rounded on its own, so the printed ones add up to 100.01%; unrounded, they make exactly 100%.
