Q1: Define mole
Answer: A mole (or mol) is defined as the amount of substance which contains equal number of particles (atoms / molecules / ions) as there are atoms in exactly 12.000g of carbon-12.
One mole of carbon-12 atom has a mass of exactly 12.000 grams and contains 6.02 × 1023 atoms.
A mol is just a number like a dozen. A dozen equals to 12 eggs , a gross of Pencil equals to 144 Pencil. Similarly, mol is equal to 6.022 × 1023(Avagadro constant). Mol is also known as chemist dozen.
