How many atoms are present in one mole of carbon?

• A. 6.022 × 10^{23}
• B. 12.01 × 10^{23}
• C. 3.01 × 10^{23}
• D. 1.00 × 10^{23}

Answer: (A)

Verified step by step guidance

1. Understand that one mole of any substance contains Avogadro's number of particles (atoms, molecules, ions, etc.).
2. Recall that Avogadro's number is a constant defined as \$6.022 \times 10^{23}$ particles per mole.
3. Since the problem asks for the number of atoms in one mole of carbon, recognize that this is directly given by Avogadro's number.
4. Note that the atomic mass of carbon (12.01 g/mol) is not needed to find the number of atoms; it is used for mass-to-mole conversions.
5. Conclude that the number of atoms in one mole of carbon is \$6.022 \times 10^{23}$ atoms, which corresponds to Avogadro's number.
