How many carbon atoms are present in one mole of 12C?

• A. 1.00 × 10^{24}
• B. 6.022 × 10^{23}
• C. 12
• D. 3.01 × 10^{23}

Answer: (B)

Verified step by step guidance

1. Understand that one mole of any substance contains Avogadro's number of entities, which is approximately \$6.022 \times 10^{23}$ particles per mole.
2. Recognize that \(^{12}C\) refers to the isotope of carbon with an atomic mass of 12, but this does not change the number of atoms in a mole; one mole of \(^{12}C\) still contains Avogadro's number of atoms.
3. Recall the definition of a mole: it is the amount of substance that contains exactly \$6.022 \times 10^{23}$ elementary entities (atoms, molecules, ions, etc.).
4. Therefore, the number of carbon atoms in one mole of \(^{12}C\) is equal to Avogadro's number, \$6.022 \times 10^{23}$ atoms.
5. Conclude that the correct answer is \$6.022 \times 10^{23}\( carbon atoms in one mole of \)^{12}C$.
