Element | Total atoms | Atomic mass | Total mass |
---|---|---|---|
Br (Bromine) | 2 | 79.904 | 159.808 |
Cr (Chromium) | 1 | 51.9961 | 51.9961 |
211.8041 |
- Mr[Br2Cr] = Ar[Br] * 2 + Ar[Cr] = 79.904 * 2 + 51.9961 = 211.8041
- Molar mass (kg/mol) = Mr[Br2Cr] : 1000 = 211.8041 : 1000 = 0.2118 kg/mol
- Bromine (Br) = 159.808 : 211.8041 * 100 = 75.451 %
- Chromium (Cr) = 51.9961 : 211.8041 * 100 = 24.549 %
