Chemistry - Mole Concept Question with Solution | TestHub

Vapour density of mixture$=\frac{{\mathrm{n}}_1{\mathrm{d}}_1+{\mathrm{n}}_2{\mathrm{d}}_2}{{\mathrm{n}}_1+{\mathrm{n}}_2}$
Here molecular weight of$\mathrm{N}{\mathrm{O}}_2$= 46
Molecular weight of${\mathrm{N}}_2{\mathrm{O}}_4=92$
Density$=\frac{\mathrm{m}\mathrm{o}\mathrm{l}\mathrm{e}\mathrm{c}\mathrm{u}\mathrm{l}\mathrm{a}\mathrm{r}\mathrm{w}\mathrm{e}\mathrm{i}\mathrm{g}\mathrm{h}\mathrm{t}}{2}$
$=\frac{2\times 46+1\times 23}{2+1}=38.3$
