We’re being asked to calculate the density of CO gas when the pressure of the gas is lowered and its temperature is raised until its volume is 2.0 L.

We will calculate the density using the ideal gas law equation:

$\overline{){\mathbit{P}}{\mathbit{V}}{\mathbf{=}}{\mathbit{n}}{\mathbit{R}}{\mathbit{T}}}$

$\frac{\mathbf{P}\overline{)\mathbf{V}}}{\overline{)\mathbf{V}}}\mathbf{=}\frac{\mathbf{nRT}}{\mathbf{V}}\phantom{\rule{0ex}{0ex}}\mathbit{P}\mathbf{=}\frac{{\mathbf{n}}\mathbf{RT}}{\mathbf{V}}$
