How many atoms are present in one mole of any element?

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

Answer: (A)

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 Avogadro's number, which defines the number of particles in one mole of a substance.
3. Avogadro's number is approximately \$6.022 \times 10^{23}$ particles per mole.
4. Therefore, one mole of any element contains \$6.022 \times 10^{23}$ atoms.
5. Compare the given options to Avogadro's number to identify the correct answer.
