Mole is the unit used to express atoms,molecules and ions.6.022×10²³ number of atoms,molecules or ions is called 1 mole.
eg 1 mole carbon atom = 6.022×10²³ carbon atoms or 12 grams
1 mole hydrogen atom=6.022×10²³ hydrogen atom or 1 gram
Number of moles = Given mass/Molar mass
Equations;
n= number of moles
W = Given mass
M = molar mass
N = Number of particles
No= Avogardo number
- n=N/M or n = N/No
- W =M×N/No

the number of particles(atoms, molecules or ions) present in one mole of any substance is fixed with a value of 6.022 x 10 to the power of 23. this is an experimentally obtained value and is called the avogadro constant.
