Molar mass calculator
Type a formula - hydrates like CuSO4·5H2O and complexes like K4[Fe(CN)6] too - and get its molar mass with the atomic masses ISC uses (Cl = 35.5, Cu = 63.5), the working, and the percentage of each element.
Answer
- Molar mass of CuSO4·5H2O
- 249.5 g mol⁻¹
Working
| Element | Atoms | Atomic mass | Mass | % by mass |
|---|---|---|---|---|
| H | 10 | 1 | 10 | 4.01 |
| Cu | 1 | 63.5 | 63.5 | 25.45 |
| O | 9 | 16 | 144 | 57.72 |
| S | 1 | 32 | 32 | 12.83 |
Add the masses: 10 + 63.5 + 144 + 32 = 249.5 g mol⁻¹.
