1.	How is mole related to (i) mass (ii) volume and (iii) number of molecules of a substance?
Answer» (i) One mole of atoms = Gram atomic mass of the element One mole of molecules = gram molecular mass Mass of one atom = {Atomic mass}/{6.023 x 10²³} (ii) Volume occupied by 1 mole of a gas at N.T.P. = 22.4 L (iii) One mole of molecules = 6.023 x 10²³ molecules.

How is mole related to (i) mass (ii) volume and (iii) number of molecules of a substance?

Answer»

(i) One mole of atoms = Gram atomic mass of the element

One mole of molecules = gram molecular mass

Mass of one atom = {Atomic mass}/{6.023 x 10²³}

(ii) Volume occupied by 1 mole of a gas at N.T.P. = 22.4 L

(iii) One mole of molecules = 6.023 x 10²³ molecules.
