Element | Total atoms | Atomic mass | Total mass |
---|---|---|---|
Fe (Iron) | 2 | 55.845 | 111.69 |
O (Oxygen) | 12 | 15.9994 | 191.9928 |

399.8778 |
- Mr[Fe2O12S3] = Ar[Fe] * 2 + Ar[O] * 12 + Ar[S] * 3 = 55.845 * 2 + 15.9994 * 12 + 32.065 * 3 = 399.8778
- Molar mass (kg/mol) = Mr[Fe2O12S3] : 1000 = 399.8778 : 1000 = 0.39988 kg/mol
- Iron (Fe) = 111.69 : 399.8778 * 100 = 27.931 %
- Oxygen (O) = 191.9928 : 399.8778 * 100 = 48.013 %
- Sulfur (S) = 96.195 : 399.8778 * 100 = 24.056 %
