Answer 1

Answer:

The number of particles in 1 mol of substance is given by the Avogadro's constant. Its value is: $N_A$= 6.02214076×10²³ mol⁻¹

Explanation:

The definition of Avogadro's constant is:

The Avogadro constant is the proportionality factor that relates the number of constituent particles in a sample with the amount of substance in that sample. Its SI unit is the reciprocal mole, and it is defined exactly as

$N_A$= 6.02214076×10²³ mol⁻¹. (per mol).

Thus, the number of particles in 1 mol of substance is given by the Avogadro's constant. Its value is: $N_A$= 6.02214076×10²³ mol⁻¹
