A gaseous mixture of H(2) and CO(2) gas ...

A gaseous mixture of `H_(2)` and `CO_(2)` gas contains 66 mass `%` of `CO_(2)` . What is the vapour density of the mixture ?

A

`6.1`

B

`5.4`

C

`2.7`

D

`10.8`

Text Solution

Verified by Experts

The correct Answer is:
C
Number of moles of `CO_(2)` in `100g` mixture `=(66)/(44)=1.5`
Number of moles of `H_(2)` in `100g` mixture `=(34)/(2)=17`
`M_("average")=(100)/(18.5)=5.40`
`V.D.=(5.4)/(2)=2.7`
