Question

What does Avogadro’s number represent? the number of atoms in 12 grams of the isotope carbon 12 the number of atoms in 120 grams of the isotope carbon 12 the number of atoms in 1 kilogram of the isotope carbon 12 the number of atoms in 1 gram of the isotope carbon 12

Answer 1

the number of atoms in 12 grams of the isotope carbon 12.

Answer 2

the number of atoms in 12 grams of the isotope carbon 12

Step-by-step 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
`N_0`.

Also, it is the number of particles in exactly 12.000 g of isotope carbon 12.

Avogadro constant:-
`N_0=6.023* 10^(23)`

Hence, correct answer:- the number of atoms in 12 grams of the isotope carbon 12
