검증된 단계별 안내1
Understand that a mole is a fundamental unit in chemistry used to count particles such as atoms, molecules, or ions.
Recall Avogadro's number, which defines the number of particles in one mole of any substance.
Avogadro's number is given as \(6.022 \times 10^{23}\) particles per mole.
Therefore, the number of atoms in 1 mole of a substance is equal to Avogadro's number, \(6.022 \times 10^{23}\) atoms.
Compare the given options to Avogadro's number to identify the correct answer.
