In chemistry, 'mole' is an essential tool for the chemical calculations. It is a basic SI unit adopted by the 14th general conference on weights and measurements in 1971. A mole contains as many elementary particles as the number of atoms present in 12g of .^(12)C. 1 mole of a gas at STP occupies 22.4 litre volume. molar volume of solids and liquids is not definite Molar mass of a substance is also called gram-atomic mass or gram molar mass. the virtual meaning of mole is plenty. heap of the collection of large numbers. 1 mole of a substance contains 6.023xx10^(23) elementary particles like atom or molecule. Atomic mass unit (amu) is the unit of atomic mass, e.g., atomic mass of single carbon is 12 amu. 5.6 litre of a gas at STP are found to have a mass of 22g. the molecvular mass of the gas is:
