# Problem: What is the density of laughing gas, dinitrogen monoxide, N2O, at a temperature of 325 K and a pressure of 113.0 kPa?

###### FREE Expert Solution

We are asked to calculate the density of laughing gas, dinitrogen monoxide, N2O, 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 :

R = universal gas constant = 0.08206 (Latm)/(molK)
= 325 K
M = 44.02 g/mol
