A reaction system in equilibrium according to reaction `2SO_(2)(g)+O_(2)(g)hArr2SO_(3)(g)` in one litre vessel at a given temperature was found to be `0.12` mole each of `SO_(2)` and `SO_(3)` and `5` mole of `O_(2)` In another vessell of one litre contains `32` g of `SO_(2)` at the same temperature. What mass of `O_(2)` must be added to this vessel in order that at equilibrium `20%` of `SO_(2)`is oxidized to `SO_(3)`?

A

`0.4125`

B

`11.6` g

C
