🤓 Based on our data, we think this question is relevant for Professor Czernuszewicz's class at UH.

We’re being asked to determine at what density will oxygen gas have the same temperature as neon gas having a density of 3.10 g/L.

We will use the **ideal gas equation** to find the density of the oxygen gas.

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

$\frac{\mathbf{P}\overline{)\mathbf{V}}}{\overline{)\mathbf{V}}}\mathbf{=}\frac{\mathbf{n}\mathbf{R}\mathbf{T}}{\mathbf{V}}\phantom{\rule{0ex}{0ex}}\mathit{P}\mathbf{=}\frac{{\mathbf{n}}\mathbf{R}\mathbf{T}}{\mathbf{V}}$

${\mathit{n}}{\mathbf{=}}\frac{\mathbf{m}\mathbf{a}\mathbf{s}\mathbf{s}\mathbf{}\left(\mathbf{m}\right)}{\mathbf{m}\mathbf{o}\mathbf{l}\mathbf{a}\mathbf{r}\mathbf{}\mathbf{m}\mathbf{a}\mathbf{s}\mathbf{s}\mathbf{}\mathbf{\left(}\mathbf{M}\mathbf{\right)}}$

At what density (in g/L) will oxygen gas have the same temperature as neon gas having a density of 3.10 g/L, with all species being held at constant pressure.

a) 4.92

b) 1.96

c) 1.40

d) 2.22

e) 3.90
