Answer 1
It’s an easy question if you know the equation my teacher always likes to say. It’s still memorable, and even two years after I first heard it said, I still remember it. Stay like that :
Sweet ᴘᴇᴇ under dirt.
The equation is this:
M = dt/p
M = molecular mass of the substance
d = gas density
r = gas constant (atm = 0.08206)
t = Temperature in K
We have just discovered that the molecular mass of Freon-11 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 to kelvin just add 273.15 to Celsius)
P = 3 atmospheres
d = ?
Just plug it all in…
137.5 = (d*0.08206*417.15)/3
d = 12.05
I hope this helps you!
