How many atoms are present in one mole of gold (Au)?

• A. 3.01 × 10^{23} atoms
• B. 6.022 × 10^{22} atoms
• C. 1.008 × 10^{24} atoms
• D. 6.022 × 10^{23} atoms

Answer: (D)

Verified step by step guidance

1. Understand that one mole of any substance contains Avogadro's number of particles (atoms, molecules, etc.).
2. Recall the value of Avogadro's number, which is approximately \$6.022 \times 10^{23}$ particles per mole.
3. Since the problem asks for the number of atoms in one mole of gold (Au), recognize that one mole of gold atoms contains exactly Avogadro's number of atoms.
4. Match the given options to Avogadro's number to identify the correct quantity of atoms in one mole of gold.
5. Conclude that the number of atoms in one mole of gold is \$6.022 \times 10^{23}$ atoms.
