A  pre-weighed vessel was filled with oxygen at NTP and weighed. It was then   evacuated, filled with `SO_2` at the same temperature and   pressure and again weighed. The weight of oxygen will be 

A

The same as that of `SO_2`

B

One-half that of `SO_2`

C

Twice that of `SO_2`

D

One-fourth that of `SO_2`

Text Solution

Verified by Experts

The correct Answer is:
B
`n_(O_2) = n_(SO_2) , (W_1)/(32) = (W_2)/(64) implies W_1 = (W_2)/(2)`.
