Q 1 :    

Equal masses of H2, O2 and methane have been taken in a container of volume V at temperature 27°C in identical conditions. The ratio of the volumes of gases H2:O2: methane would be                [2014]

  • 8 : 16 : 1

     

  • 16 : 8 : 1

     

  • 16 : 1 : 2

     

  • 8 : 1 : 2

     

(3)

According to Avogadro's hypothesis, ratio of the volumes of gases will be equal to the ratio of their number of moles.

So, no. of moles=MassMol. mass

nH2=w2;  nO2=w32;  nCH4=w16

So, the ratio is w2:w32:w16  or  16:1:2
