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}
Verified step by step guidance1
Understand that one mole of any substance contains Avogadro's number of entities, which is approximately \(6.022 \times 10^{23}\) particles per mole.
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.
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.).
Therefore, the number of carbon atoms in one mole of \(^{12}C\) is equal to Avogadro's number, \(6.022 \times 10^{23}\) atoms.
Conclude that the correct answer is \(6.022 \times 10^{23}\) carbon atoms in one mole of \(^{12}C\).
