Question

what do you mean by Avogadro number

Answer 1

Avogadro number :- according to Avgadro ,
no of atoms /ions /molecule in one mole = 6.023 × 10²³

here 6.023 × 10²³ is known as Avpgadro number .

Answer 2

the avagadro number =6.022×10²³.
according to Avagadro he told that 1 mole of an element (it may be a gas , liquid or gas)contains 6.022×10²³ atoms.it was also experimentally proved.also by researches it is found that 1 gram atomic mass of an element contains 6.022×10²³ atoms.1gram atomic mass means 1 unit atomic mass of an element in grams.with the help of his law many arguments came over the difference between an atom and an element.
also no. of moles means the no. of atoms, ions or molecules in an element.
