2H2O → 2H2 (g) + O2 (g). If a given experiment results in 2500 cm3 of H2 being produced, what volume of O2 is liberated at the same time under the same conditions of temperature and pressure.

Mass of a H2O molecule = 2*1 + 16 = 16+2=18 u
Ratio of mass of hydrogen : oxygen = 1 : 8
This means that amount of oxygen produced us always 8 times more than amount of hydrogen produced in this reaction.
Volume of O2 liberated = 2500*8=20000 cm3
20000cm3= 20000 ml = 20 litres
