<h2>Answer:</h2>
The number of particles in 1 mol of substance is given by the Avogadro's constant. Its value is:
= 6.02214076×10²³ mol⁻¹
<h2>Explanation:</h2>
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
= 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:
= 6.02214076×10²³ mol⁻¹
