We are asked to calculate the density of laughing gas, dinitrogen monoxide, N_{2}O, at a temperature of 325 K and a pressure of 113.0 kPa.

Use the modified ideal gas law to solve for density:

$\overline{){\mathbf{d}}{\mathbf{=}}\frac{\mathbf{PM}}{\mathbf{RT}}}$

**We can now calculate the ****density :**

$\mathbf{P}\mathbf{}\mathbf{=}\mathbf{}\mathbf{}\mathbf{113}\mathbf{.}\mathbf{0}\mathbf{}\overline{)\mathbf{kPa}\mathbf{}}\mathbf{\times}\frac{\mathbf{1}\mathbf{}\mathbf{atm}}{\mathbf{101}\mathbf{.}\mathbf{325}\mathbf{}\mathbf{}\overline{)\mathbf{kPa}\mathbf{}}}\mathbf{}\mathbf{=}\mathbf{}\mathbf{1}\mathbf{.}\mathbf{115}\mathbf{}\mathbf{atm}$**R** = universal gas constant = 0.08206 (L∙atm)/(mol∙K)**T **= 325 K**M** = 44.02 g/mol

What is the density of laughing gas, dinitrogen monoxide, N_{2}O, at a temperature of 325 K and a pressure of 113.0 kPa?
