Element | Total atoms | Atomic mass | Total mass |
---|---|---|---|
Cr (Chromium) | 1 | 51.9961 | 51.9961 |
K (Potassium) | 2 | 39.0983 | 78.1966 |
O (Oxygen) | 4 | 15.9994 | 63.9976 |
194.1903 |
- Mr[CrK2O4] = Ar[Cr] + Ar[K] * 2 + Ar[O] * 4 = 51.9961 + 39.0983 * 2 + 15.9994 * 4 = 194.1903
- Molar mass (kg/mol) = Mr[CrK2O4] : 1000 = 194.1903 : 1000 = 0.19419 kg/mol
- Chromium (Cr) = 51.9961 : 194.1903 * 100 = 26.776 %
- Potassium (K) = 78.1966 : 194.1903 * 100 = 40.268 %
- Oxygen (O) = 63.9976 : 194.1903 * 100 = 32.956 %
