Sure, let's find out which value corresponds to the number of particles in 1 mol of a substance.
The number of particles in one mole of any substance is given by Avogadro's number. Avogadro's number is a fundamental constant and its value is:
[tex]\[ 6.02 \times 10^{23} \][/tex]
This number represents the number of atoms, molecules, or ions in one mole of a substance. Given the options:
1. [tex]\( 6.02 \times 10^{21} \)[/tex]
2. [tex]\( 6.02 \times 10^{22} \)[/tex]
3. [tex]\( 6.02 \times 10^{23} \)[/tex]
4. [tex]\( 6.02 \times 10^{24} \)[/tex]
The correct choice that matches Avogadro's number is:
[tex]\[ 6.02 \times 10^{23} \][/tex]
Thus, the number of particles in 1 mol of a substance is:
[tex]\[ 6.02 \times 10^{23} \][/tex]
So, the correct choice is:
[tex]\[ \boxed{3} \][/tex]
