Question

How will you proved that water contains hydrogen and oxygen in ratio 2:1 by volume?

Answer 1

for proving that water contains hydrogen and oxygen in ratio 2 is to 1 we have to use the process of electrolysis and it should be a closed system so that none of the gases escape out the oxygen and hydrogen it should not escape and then we should conserve use the property of conservation of mass then we will find that the hydrogen is half of the a mass of the oxygen
