Chemistry - Ideal Gas Question with Solution | TestHub

$\mathrm{D}\mathrm{e}\mathrm{n}\mathrm{s}\mathrm{i}\mathrm{t}\mathrm{y}=\frac{\mathrm{m}\mathrm{a}\mathrm{s}\mathrm{s}}{\mathrm{v}\mathrm{o}\mathrm{l}\mathrm{u}\mathrm{m}\mathrm{e}}$
For a sealed rigid container mass as well as volume remains a constant hence the density remains same even if the temperature changes.
