For an element, how does Avogadro’s number connect the atomic and macroscopic scales?

Question

(1 point)
It describes the number of moles in 1 gram of an element.
It describes the number of atoms in 1 gram of an element.
It describes the number of grams in 1 mole of an element.
It describes the number of atoms in 1 mole of an element.

Answer 1

The correct statement is: It describes the number of atoms in 1 mole of an element.

Avogadro's number, approximately \(6.022 \times 10^{23}\), is the number of atoms, molecules, or particles in one mole of a substance, connecting the atomic scale to the macroscopic scale by allowing us to count particles in bulk amounts.
