Final answer:
Avogadro's number is equal to 6.02 × 10^23 particles (atoms or molecules). A mole of any substance always contains 6.02 × 10^23 particles, regardless of the element or substance.
Step-by-step explanation:
Avogadro's number is equal to 6.02 × 1023 particles (atoms or molecules). A mole of any substance always contains 6.02 × 1023 particles, regardless of the element or substance. Therefore, all of the options listed are equal to 1 mole.
