A and `B` are two idential vessels. `A` contains `15 g` ethane at `1 atm` and `298 K`. The vessel `B` contains `75 g` of a gas `X_(2)` at same temperature and pressure. The vapour density of `X_(2)` is :

A

75

B

150

C

37.5

D

45

Text Solution

Verified by Experts

The correct Answer is:
A
acc of Avogadro.s law
`""^(n)C_(2)H_(6)=""^(n)x_(2)`
`(15)/(30)=(75)/(""^(M)X_(2)) therefore ""^(M)X_(2)=150`
`therefore" V.D "=("M. wt")/(2)=(150)/(2)=75`
