How many carbon atoms are present in one mole of carbon?

• A. 12.01 × 10^{23}
• B. 1.00 × 10^{6}
• C. 3.01 × 10^{23}
• D. 6.022 × 10^{23}

Answer: (D)

Verified step by step guidance

1. Understand that one mole of any substance contains Avogadro's number of entities (atoms, molecules, etc.).
2. Recall that Avogadro's number is approximately \$6.022 \times 10^{23}$ entities per mole.
3. Since the problem asks for the number of carbon atoms in one mole of carbon, the answer corresponds directly to Avogadro's number.
4. Recognize that the molar mass of carbon (12.01 g/mol) is not needed to find the number of atoms, but it helps relate mass to moles.
5. Conclude that one mole of carbon contains \$6.022 \times 10^{23}$ carbon atoms.
