Question

Explain the mole concept. What is the importance of mole concept?

Answer 1

Atoms are tiny particles and have a very small weight. To calculate the particles that have a small size,the mole concept was introduced.
MOLE CONCEPT

$\bullet$ The mole is an unit of amount.

$\bullet$ It is defined as the mass of substance containing the same number of fundamental units.

$\bullet 1$ mole $=6.022\times {10}^{23}=N_A$ (particles) = Avogadro Number
$mole=\frac{givenmass}{molarmass}=\frac{givenno.ofparticles}{Avagadronumber}$

IMPORTANCE:-

$\bullet$ It is important because it allows chemist to work with micro units and amounts.

$\bullet$ You can easily change mole to gram or gram to mole.
