Lösung:
On the to the Periodic system ('PSE') are u.a. The Masses The Atoms indicated. That 's it . is At the same time, Elements Bromine of which: other The Indication 79.904. This Indication is The following masses to Interpreting: Either is Questioned, which Weight a only Bromate has (: 79.904 u) or which Weight a Mol Manufacture from materials of any heading (: So what do you mean? not It 's just … a only Bromate, but a Mol = 6.022·1023 Manufacture from materials of any heading) have (: 79.904 g).
One of them 'u' is So what do you mean? One Mass indication (1 u = 1.66·10-27of which:), g/mol is The Mass indication for 1 mol (or 6.022·1023) .
