What is the density of ethanol-water mixtures?
Water-Ethanol mixture
| ethanol in water at T = 15.6 oC | Density in g/mL | |
|---|---|---|
| mass% | volume% | at T = 20.0 oC |
| 0 | 0 | 0.998 |
| 5 | 6.2 | 0.989 |
| 10 | 12.4 | 0.981 |
How does the density of 50% ethanol solution compare with the density of pure water?
The hydrogen bonding in pure ethanol is shown below. Pure ethanol has a lower density than water, 0.789 g/mL at 25 deg as opposed to 1.000 g/mL for pure water. The density of an ethanol solution in water will have a density lower than water.
What is the density of 70% ethyl alcohol?

How do you find the density of ethanol?
Determining the density of ethanol-water solutions as a function of the volume concentration of the ethanol. The density of a liquid is defined as the ratio = m V (I), m: mass, V: volume.
Why does ethanol have a lower density than water?
Although alcohol also contains oxygen atoms, its molecules are not able to pack together as tightly as water molecules, and so it is less dense than water.
How does ethanol affect density?
Ethanol of the same Volume has a lower Weight and therefore a lower Relative Density to Water as a base reference. The simple answer is that Ethanol has a lower density than Water. The relationship Density=weight/volume, or more generally, Density= mass/volume is easily enough understood.
What is ethanol density?
789 kg/m³
Ethanol/Density
Does ethanol float on water?
EtOH will neither sink or float in water. It will DISSOLVE in water. Mainly the molecules of ethanol, CH3CH2OH will be fairly soluble in H2O.
Is ethanol more volatile than water?
Detailed Solution. Alcohols are more volatile than water because they are less polar. Ethanol is much less “sticky” and more readily enters the gaseous phase, hence it is more volatile.
