# Problem: The density of krypton gas at 1.21 atm and 50.0°C is ________ g/L. A) 0.295 B) 7.65 C) 3.82 D) 0.262 E) 0.0456

###### FREE Expert Solution

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

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

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