Elemental Bromine exists as a diatomic molecule, its atomic number is 35 and its atomic weight is 79.904. A molecule would therefore have a weight of 159.808.

A Mole is defined as the amount of any substance that contains as many elementary entities (in this case diatomic molecules) as Avogadro's constant ( 602,214,150,000,000,000,000,000).A mole of Bromine would therefore weigh 159.808 grams.

Therefore 46.7 grams of Bromine would contain

(46.7)/159.808)*602,214,150,000,000,000,000,000

Which is 0.292225670804966 * 602,214,150,000,000,000,000,000

Which = 175,982,433,951,992,400,000,000 molecules.
