Answer: A mole of Cu atoms has the same number of atoms as a mole of He atoms.

Step-by-step explanation:

In one mole of atoms there are
6.02* 10^(23)
numbers of atoms. Given by Amedeo Avogadro. Also know as Avogadro number. It remain constant for every 1 mole of substance.


N_A=6.02* 10^(23) atoms


1 mole=6.02* 10^(23) \text{atoms or molecule or ions or particles}

The correct statement is"A mole of Cu atoms has the same number of atoms as a mole of He atoms."
