Equal masses of H2,O2 and methane have been taken in a container of volurne (V) at temperature 27°C in identical conditions. The ratio of the volumes of gases H2:O2:CH4 would be

Equal masses of H2,O2 and CH4 are taken in volume (V )of container, volume of gas ∝ number of moles (Avogadro's law)Volume of H2 : Volume of O2 : Volume of CH4=w2:w32:w16MH2=2,MO2=32,MCH4=16= 16 : l : 2
