One mole of particles of any substance contains how many particles?

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

Answer: (A)

Verified step by step guidance

1. Understand that the problem is asking about the number of particles in one mole of any substance, which relates to a fundamental constant in chemistry.
2. Recall Avogadro's number, which defines the number of particles (atoms, molecules, ions, etc.) in one mole of a substance.
3. Avogadro's number is expressed as \$6.022 \times 10^{23}$ particles per mole.
4. This means that one mole of any substance contains exactly \$6.022 \times 10^{23}$ particles, regardless of the type of particle.
5. Therefore, the correct answer corresponds to Avogadro's number, \$6.022 \times 10^{23}$.
