This is an easy question if you know the equation that my teacher always loves to say. It is always memorable, and even two years since I first heard him say it, I still remember. It goes like this:
Moles pee under the dirt.
The equation is this:
M = drt/p
M = molecular mass of substance
d = density of gas
r = gas constant (atm = 0.08206)
t = Temperature in K
We just find out that Freon-11's molecular mass is:
C = 12
F = 19
Cl = 35.5
12+19+(3*35.5) = 137.5 = M (in the equation)
R = 0.08206
T = 417.15 K (to convert into kelvin, just add 273.15 to the Celcius)
P = 3 atm
d = ?
Just plug it all in...
137.5 = (d*0.08206*417.15)/3
d = 12.05
I hope I helped!
