One mole of any substance contains how many particles?
A
3.011 × 10^23
B
6.022 × 10^22
C
6.022 × 10^23
D
1.204 × 10^24
Correct Answer: Option C — 6.022 × 10^23
Explanation:
Avogadro's number, 6.022 × 10^23, defines the number of particles (atoms, molecules, or ions) present in one mole of any substance, forming the fundamental basis for stoichiometric calculations in chemistry.
