Question

prove that 1mole of any substnce contain avogadro number of particles

Answer 1

$\star$ Concept

_________________________________

Avogadro's number is an absolute number there are 6.022 × 10²³ elementary entities in 1 mole.This can also be written as 6.022 × 10²³ mol¹. The mass of one mole of substance is equal to the substance 's molecular weight

_________________________

Prove :

According to the mole concept ,

$\sf\huge\implies$ 1 mole of any substance contains particle equal to avogadro number .

$\rightarrow$1 mole of $O_2$ have 32 g of mass.

So , 32 gram of oxygen contains Avogadro number of oxygen particles .

$\huge\sf\implies$ Hence proved.
