검증된 단계별 안내1
Understand that the mole is a fundamental unit in chemistry used to count particles such as atoms, molecules, or ions.
Recall that one mole of any substance contains a specific number of particles, known as Avogadro's number.
Avogadro's number is defined as \(6.022 \times 10^{23}\) particles per mole.
This means that one mole of any element or compound contains exactly \(6.022 \times 10^{23}\) atoms, molecules, or ions.
Therefore, the number of particles in one mole is \(6.022 \times 10^{23}\), which is the key to converting between moles and number of particles.
