• A. 3.14 × 10^{8}
• B. 1.00 × 10^{6}
• C. 9.81 × 10^{2}
• D. 6.022 × 10^{23}

Answer: (D)

Verified step by step guidance

1. Understand that a mole is a fundamental unit in chemistry used to count particles such as atoms, molecules, or ions.
2. Recall that the numeric value of a mole is defined by Avogadro's number, which represents the number of particles in one mole.
3. Avogadro's number is a very large number because atoms and molecules are extremely small and numerous.
4. The value of Avogadro's number is approximately \$6.022 \times 10^{23}$ particles per mole.
5. Therefore, the numeric value of a mole for atoms or molecules is \$6.022 \times 10^{23}$.
