GSEB - Class 9 Chapter - 4.Properties of Matter Page 59

Answer 1

mole is a particle of a matter it might be pure or impure molar mass is the mass of the mole........

Answer 2

Mole is often tough to understand but it can be understood easily.
Mole is just a unit of comparison derived by scientists for ease such as DOZEN.
Just like Dozen is a unit comprising of any 12 things.
For example- 1 Dozen Bananas = 12 Bananas.
Similarly,

$1 \: mole = 6.023 \times {10}^{23} entities$
There is no unit for mole as Mole Is Itself A Unit.

Molar Mass of an element is actually the Atomic Mass or simply mass of the Element.

Good Luck! Hope it helps
