Vapour density of the equilibrium mixture of NO_(2) and N_(2)O_(4) is

1.	Vapour density of the equilibrium mixture of NO_(2) and N_(2)O_(4) is found to be 40 for the equilibrium N_(2)O_(4) harr 2NO_(2). From this information answer the following Percentage of NO_(2) in the mixture is
Answer» `26%` `24%` `28%` `22%` SOLUTION :`underset(1-alpha)(N_(2)O_(4)) harr underset(2alpha)(2NO_(2))` `%=(2alpha)/(1+alpha)=(2 XX 0.15)/(1.15)=0.26`
