Answer:
Pure Glycol
For example,
Antifreeze will freeze at minus 34 degrees.
Also prevents your car from freezing up because of the Pure Gycol in it.

The statement "<span>The liquid-vapor equilibrium of a substance can be disturbed by cooling the substance" is false. The substance must be heated in order to get the vapor phase of that substance.</span>
1 mol --- 22,4 dm³
2,1 mol --- X
X = 2,1×22,4
X = 47,04 dm³ = 47,04 L
