Which of the following is NOT equal to Avogadro's number?

Group of answer choices

6.02x10 to the power of 23 molecules of CO

The mass of 2 moles of Br subscript 2

The number of atoms in 1 mol of Au

The number of molecules in 1 mol of N subscript 2

The mass of 2 moles of Br subscript 2

Explanation:

1 mol of any substance contains 6.02*10^23 particles of this substance. This number is called Avogadro's number.

6.02x10 ^ 23 molecules of CO - Avogadro's number.

The mass of 2 moles of Br2 - 2 moles than it has 2 * Avogadro's number.

The number of atoms in 1 mol of Au - 1 mol has Avogadro's number of atoms of Au

The number of molecules in 1 mol of N subscript 2 - has Avogadro's number of molecules N2.

The mass of 2 moles of Br subscript 2.

Explanation:

Avogadro's number (6.02x10^23) is the number of molecules/atoms in one mole of an element or compound.
