Equal masses of He, O_(2) and SO_(2) are taken in a closed container.

1.	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
Answer» `1:2:8` `8:16:1` `16:2:1` `1:4:16` Solution :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`
