Specific gravity is simply the ratio of the specific weight of a given liquid to the specific weight of water at 4° C (γwater = 9.81 kN/m3 or 62.4 lb/ft3). Related titles. Further refinements from Andreas Volk to density of pure water, and the temperature-dependence of the contraction of the mixture. Glycerin’s viscosity is very high, which is a very prominent characteristic of glycerin. 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.

Glycerol (/ ˈ ɡ l ɪ s ə r ɒ l /; also called glycerine or glycerin) is a simple polyol compound. The higher concentration of these salts, the higher the concentration of glycerin, the lower viscosity. will sink in water but it will float on mercury. moles C3H8O3 = 0.02750 moles (this is from the fact that 1.000 L was made), mass of water = 998.8 ml x 0.9982 g/ml = 997.00 g, moles H2O = 997.00 g x 1 mol/18 g = 55.39 moles H2O, molality = moles solute/kg solvent = 0.02750 moles/0.99700 kg = 0.02758 m, mole fraction = 0.02750 mol/(0.02750 mol + 55.39 mol) = 0.00496, % by mass: 0.0275 mol x 92.094 g/mol = 2.53 g glycerol + 997 g H2O = 999.5 g, % by mass = 2.53 g/999.5 g (x100%) = 0.253%, ppm = 2.53 g/L x 1000 mg/g = 2530 mg/L = 2530 ppm. The density changes as the change of temperature. M3: Modified on 20 December 2017. The density of water at 20.0∘C is 0.9982 g/mL. 2. the relationship between the concentration of glycerol aqueous solution and the relative density at low temperature is shown in table 2.3.
