1 mole of a substance consists of Avogadro number (6.023 * 10²³ ) of molecules in it. There are many properties of substances that are based on moles.
A mole of any idea gas is supposed to occupy a fixed volume at a standard pressure and temperature.
P V = n R T
n = number of moles of a gas T = absolute temperature
P = pressure , V = volume, R = gas constant
In a chemical reaction like :
Na OH + H Cl ==> H2 O + Na Cl
One mole of sodium hydroxide and one mole of Hydrochloric acid react to form one mole of water and 1 mole of salt.
