Question

calculate the number of atoms of Br in 1.00 moles of Br gas

Answer 1

So we start with Avogadro's number. \[6.02 * 10^{23}\]
This gives us particles per mol. Bromine gass contains 2 atoms. \[Br _{2}\]
So we multiply Avogadro's number, by the number of moles, by the amount of atoms in the molecule.

Answer 2

\[1* (6.02 * 10^{23}) * 2 =\]
