Verified step by step guidance1
Understand that 1 mole of any substance contains Avogadro's number of entities (atoms, molecules, etc.). Avogadro's number is approximately \(6.022 \times 10^{23}\) entities per mole.
Recognize that the problem asks for the number of carbon atoms in 1 mole of carbon atoms, so the quantity is directly related to Avogadro's number.
Recall the definition: 1 mole of carbon atoms = \(6.022 \times 10^{23}\) carbon atoms.
Note that the given options include values close to Avogadro's number and other numbers that are not relevant to the mole concept (like \(1.00 \times 10^{6}\) atoms or 12.01 atoms, which is the atomic mass of carbon, not the number of atoms).
Conclude that the number of carbon atoms in 1 mole of carbon is equal to Avogadro's number, \(6.022 \times 10^{23}\) atoms.
