A pre-weighed vessel was filled with oxygen at `NTP` weighted. It was the evacuated, filled with `SO_(2)` at the same temperature and pressure, and again weighted. The weight of oxygen will beA. The same as that of `SO_(2)`B. `(1)/(2)` that of `SO_(2)`C. Twice that of `SO_(2)`D. One-fourth that of `SO_(2)`

Answer» Correct Answer - B
`("M.wt.of".O_(2))/("M.wt. of" SO_(2))implies (M_(1))/(M_(2))implies(32)/(64)= (1)/(2)`
The weight of oxygen will be `(1)/(2)` that of `SO_(2)`
