The vapoour density of a mixture containing `NO_(2)` and `N_(2)O_(4)` is 38.3 at 300 K. the number of moles of `NO_(2)` in 100 g of the mixture is approximately

Text Solution

Verified by Experts

`N_(2)O_(4)(g)iff2NO_(2)(g)`
`M_(mix)=2xx38.3=76.6`
`N_(2)O_(4)iff2NO_(2)`
`{:(t=0,a,0),(t=t,a-aalpha,2aalpha):}`
no. of moles of `NO_(2)=`"no. of moles of" N`O_(2)=2_(aalpha)=(2xx100xx0.2)/(92)=0.435`
