Question

Define molar mass and avogadro constant

Answer 1

Definition of Avogadro's number. : the number 6.022 × 1023 indicating the number of atoms or molecules in a mole of any substance. — called also Avogadro number.

Molar Mass : It is defined as the mass of a given substance (chemical element or chemical compound) divided by its amount of substance. The base SI unit for molar mass is kg/mol

Answer 2

$\star\:\sf\red {Molar\:Mass}$

The molar mass of an element is equal to the numerical value of atomic mass. However,in case of molar mass,the units change from 'u' to 'g'. The molar mass of an atom is also known as gram atomic mass.

$\star\:\sf\red {Example}$

The atomic mass of carbon = 12 atomic mass units.So,the gram atomic of carbon - 12 gram.

$\star\:\sf\green{Avogadro \:Number }$

The number of the particles present in one mole of any substance is equal to $\sf \orange{6.022 \times {10}^{23} }$.This is called avogardo's number or avogardo's constant.
