WebExplain why. a) As each mole consists of same number of atoms or molecules i.e. (6.022 ×10^23) , therefore one mole of H2, one mole of O2 and one mole of F2 have same number of molecules. b) Mass of 1 mole of substance is known as its molar mass. Thus , mass of 1 mole of H2 = 2× (1.0 g/mol) = 2.0 g/mol.
