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 K4[Fe(CN)6]
- 368 g mol⁻¹
Working
| Element | Atoms | Atomic mass | Mass | % by mass |
|---|---|---|---|---|
| C | 6 | 12 | 72 | 19.57 |
| Fe | 1 | 56 | 56 | 15.22 |
| K | 4 | 39 | 156 | 42.39 |
| N | 6 | 14 | 84 | 22.83 |
Add the masses: 72 + 56 + 156 + 84 = 368 g mol⁻¹.
