All the following are equal to Avogadro's number EXCEPT a. the number of atoms of bromine in 1 mol Br₂.

1 mol Br₂ contains Avogadro’s number of molecules of Br₂.

However, each molecule contains two atoms of Br, so there are

2 × Avogadro’s number of Br atoms in 1 mol Br₂.

Avogadro's number simply means the number of atoms or molecules in one mole of a substance, Hence, since the [tex] Br_{2} [/tex] contains two atoms, hence, it is twice the Avogadro number. Hence, answer is A.

  • The Au has only one atom, hence its number of atoms is equal to the Avogadro number.

  • The number of nitrogen molecule is 1, therefore, it will also be equal to the Avogadro number.

  • 1 molecule of CO will also be equal to the Avogadro number.

Therefore, the number of atoms in [tex] Br_{2} [/tex] will be 2 times the Avogadro number.
