the number of hydrogen molecules produced is twice the number of oxygen molecules. So, electrolysis of water produces 2 volumes of hydrogen gas and 1 volume of oxygen gas because the ratio of hydrogen and oxygen elements in water is 2:1 by volume.
the mass of two atoms of hydrogen will be 2amu and one atom of oxygen will be 16 amu so there are given in 8:1 ratio by mass
