NaBr heated in Na vapor produced nonstoichiometric compounds;i.e., the atomic ratios are not whole numbers. The additionaluptake of Na atoms occurs by the reaction: Na -> Na++ e-, where the Na+ ions sit on vacantNa+ sites and the e- sits on vacantBr- sites. If a maximum amount of Na is taken up by thematerial in question 1 (NaBr with a= 5.94Ã… and observed density=3.203g/cc), what would be the formula of the material that isformed? Â
