All of the following are equal to avogadro's number except a. the number of atoms of bromine in 1 mol br2 b. the number of atoms of gold in 1 mol au c. the number of molecules of nitrogen in 1 mol n2 d. the number of molecules of carbon monoxide in 1 mol co

Avogadro's number simply means the number of atoms or molecules in one mole of a substance, Hence, since the contains two atoms, hence, it is twice the Avogadro number. Hence, answer is A.

Therefore, the number of atoms in will be 2 times the Avogadro number.

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.
