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

Options

A. `1:2:8`
B. `8:16:1`
C. `16:2:1`
D. `1:4:16`

Answer

D

Explanation

For a mixture of non-reacting gases, partial pressure `prop` number of moles. If m is the mass of each gas taken, then
`n_(He)=(m)/(4), n_(O_(2))=(m)/(32), n_(SO_(2))=(m)/(64)`
`:. "Ratio " n_(He):n_(O_(2)):n_(SO_(2))=(1)/(4):(1)/(32):(1)/(64)=16:2:1`
