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

Answer: (D)

Verified step by step guidance

1. Understand that the question is asking for the number of particles in one mole of any substance, which is a fundamental concept in chemistry related to the mole unit.
2. Recall that one mole of a substance contains Avogadro's number of particles, which can be atoms, molecules, ions, or other entities depending on the substance.
3. Avogadro's number is a constant defined as \$6.022 \times 10^{23}$ particles per mole.
4. This means that for any substance, one mole will always contain exactly \$6.022 \times 10^{23}$ particles, regardless of the type of particle.
5. Therefore, the correct answer to the question is the value of Avogadro's number: \$6.022 \times 10^{23}$ particles.
