Answer:
the number of atoms in 12 grams of the isotope carbon 12
Explanation:
Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by [tex]N_0[/tex].
Also, it is the number of particles in exactly 12.000 g of isotope carbon 12.
Avogadro constant:- [tex]N_0=6.023\times 10^{23}[/tex]
Hence, correct answer:- the number of atoms in 12 grams of the isotope carbon 12
