Question

Equal masses of `He, O_(2)` and `SO_(2)` are taken in a closed container. The ratio of the partial pressures of gases `He, O_(2)` and `SO_(2)` would be
A. `1 : 2 : 8`
B. `8 : 16 : 1`
C. `16 : 8 : 1`
D. `16 : 2 : 1`

Answer 1

For mixture of non-reacting gases,
partial pressure `alpha` number of moles
`n_(He) : n_(O_(2)) : n_(SO_(2)) = 1//4 : 1//32 : 1//64`
`= 16 : 2 : 1`
`p_(He) : p_(O_(2)) : p_(SO_(2)) = 16 : 2 : 1`
