Bromine I 'm going . in The Nature as Mixed The Both Stable isotopes 79Br and 81Br on. Hfrequency: 79Br to 50.65%, m = 78.918338 u. Calculate from The Average molar mass of the Manufacture in which all the materials used are: Now The Hfrequency and The Weight of the 81Br in u and g/mol.
Hinweis: The molar mass of the Manufacture in which all the materials used are: is (PSE) 79.904 u Responsibility. 79.904 g/mol
Lösung: Hfrequency of the second Isotopes: 100 – 50.65% = 49.35%
This means that: 0.5065·78.918338 u + 0.4935· x u = 79.904 u
x = 80.9156 u Responsibility. 80.9156 g/mol
