Equal masses of H2 O2 and methane have ...

Equal masses of `H_2 O_2` 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 `H_2:O_2`: methane, would be

A

`8 :16 :1`

B

`16 :8 :1`

C

`16 :1 :2`

D

`8 :1 : 2`

Text Solution

Verified by Experts

The correct Answer is:
C
According to Avogadro.s hypothesis, ratio of the volumes of gases will be equal to the ratio of their no. of moles. So,
no of moles ` =("Mass")/("Mol. Mass") , n_(H_2) =(w)/(2) , n_(O_2) = (w)/( 32) , n_(CH_4) = (w)/(16 )`
So , the ratio is ` (w)/(2) : (w)/(32) , (w)/(16 ) or 16 : 1 :2 `
