In the context of the mole concept, how many particles (atoms, molecules, or ions) are present in one mole of any element or compound?

• A. 6.022 × 10^{22}
• B. 1.00 × 10^{6}
• C. 3.01 × 10^{23}
• D. 6.022 × 10^{23}

Answer: (D)

Verified step by step guidance

1. Understand that the mole is a fundamental unit in chemistry used to count particles such as atoms, molecules, or ions.
2. Recall that one mole of any substance contains a specific number of particles, known as Avogadro's number.
3. Avogadro's number is defined as \$6.022 \times 10^{23}$ particles per mole.
4. This means that one mole of any element or compound contains exactly \$6.022 \times 10^{23}$ atoms, molecules, or ions.
5. 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.
