Correct answer: C. 6.023x10 ^23
- A. 6.023x10^22
- B. 6.023x10^21
- C. 6.023x10 ^23
- D. 4.02x10^23
Explanation
One mole of any substance contains 6.023 x 10^23 particles (atoms, molecules, or ions). This number is known as the Avogadro's number (NA).Avogadro's number is a fundamental constant in chemistry, and it is used to relate the amount of a substance to the number of particles it contains.
