What is the density of glycerol?
1.26 g/cm³
Glycerol/Density
Note that glycerol with 1.26g/cm3 is much denser than water and, therefore, a 50% (v/v) solution will be very different from a 50% (w/v) solution.

What is reason for high viscosity of glycerol?
Hence, both glycerol and water can form strong intermolecular hydrogen bonds, but glycerol can form more hydrogen bonds per molecule than water. The higher extent of hydrogen bonding in glycerol thus makes glycerol more viscous than water.
What temp does glycerol freeze?
Please note that although pure glycerin freezes at 17°C, it will typically supercool at temperatures below this, and become very thick instead of freezing. If trying to achieve acceptable performance at low temperatures an ideal mixture of glycerin/water is between 60/40 and 70/30, as can be see in the graph below.
Does glycerol have higher density than water?
Glycerol (or Glycerin) is more dense than water (1.26 g/cc). One could argue that glass is a very slow-moving, viscous liquid (although it has lots of properties of a solid, like rigidity). It’s more dense than water.
Whats the freezing point of glycerol?
Boiling and freezing points of glycerine aqueous solutions
| Glycerine to Water Concentration (% by mass, weight) | Specific Gravity (at 60oF, 15.6oC) | Freezing Point |
|---|---|---|

| 90 | 1.240 | 29 |
| 80 | 1.213 | -5 |
| 70 | 1.185 | -38 |
What is the density of glycerol in g ml?
1.26g/ml
Glycerol is often used as a component in electrophoresis loading buffers because of its density (1.26g/ml).

Why is glycerol more dense than water?
Water is very small, and can form 4 hydrogen bonds per molecule. Glycerol has three hydroxide groups…but shouldn’t the nonpolar 3 carbon backbone, and a larger general size, prevent it from packing more tightly than water? It’s important to remember that its molecular weight is greater by a difference of 74 g/mol.
How does temperature affect liquid viscosity?
The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature. Thus, upon heating, liquids flow more easily, whereas gases flow more sluggishly.
How does glycerol affect freezing point?
The boiling points of glycerine (also called glycerin or glycerol) water mixtures are reduced with increased amounts of glycerine. The freezing points are reduced until glycerine concentration is 66.7 % (mass). Increasing the glycerine concentration above 66.7 % will increase the freezing point as indicated below.
What is the density of glycerol per cubic meter?
Precision: Glycerol weighs 1.2613 gram per cubic centimeter or 1 261.3 kilogram per cubic meter, i.e. density of glycerol is equal to 1 261.3 kg/m³; at 20°C (68°F or 293.15K) at standard atmospheric pressure.
How much does one gram of glycerol weigh?
Glycerol weighs 1.2613 gram per cubic centimeter or 1 261.3 kilogram per cubic meter, i.e. it’s density is equal to 1 261.3 kg/m³.
How is viscosity of glycerol related to temperature?
When there is moisture in the glycerol, the viscosity calculation formula is as follows: In the formula, η is water containing c*% (mass) and the dynamic viscosity (freezing point = 273.16K) when the thermodynamic temperature is T. In addition, glycerin’s viscosity increases rapidly with the increase of pressure, as well as its growth rate.
What is the percentage of glycerol in sweet water?
High-pressure splitting: Water and fat are fed into a splitting column in counter-current fashion at 2 – 6 MPa and 220 – 260 deg C, leading to about a 15% solution of glycerol in water, known as sweet water. This glycerol is marketed as 88% saponification- or hydrolysis-crude glycerol.
