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}$.
Recognize that the problem asks for the number of carbon atoms in 1 mole of carbon atoms, which means we are looking for the number of atoms in exactly one mole.
Recall the definition of a mole: 1 mole of carbon atoms contains exactly \$6.022 \times 10^{23}$ carbon atoms.
Note that the other numbers given (such as \$3.011 \times 10^{23}\( or \)1.00 \times 10^{24}$) are not the standard Avogadro's number and thus are not correct for the number of atoms in 1 mole.
Conclude that the number of carbon atoms in 1 mole of carbon is \$6.022 \times 10^{23}$ atoms, which is Avogadro's number.
