# Problem: At 0°C and 2 atm, nitrogen gas’s density is:A. 5.00 g/L B. 3.9 g/L C. 2.50 g/L D. 1.2 g/L E. 2 g/L

###### FREE Expert Solution

We are asked to calculate the density of nitrogen at 0°C and 2 atm.

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

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

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