# What is the density of Freon-11 (CFCl3) at 166 degrees Celsius and 5.92 atm?

##### 1 Answer

The density of Freon-11 is 22.6 g/L.

#### Explanation:

Freon-11 is a compound with formula

We can use the **Ideal Gas Law** to determine its density.

#color(blue)(bar(ul(|color(white)(a/a)pV = nRTcolor(white)(a/a)|)))" "#

Since

#pV = (m/M)RT#

We can rearrange this to

#pM = m/VRT#

But

∴

and

#color(brown)(bar(ul(|color(white)(a/a)ρ = (pM)/(RT)color(white)(a/a)|)))" "#

In your problem,

∴
