Glycerol is a syrupy liquid often used in cosmetics and soaps. a 2.50-l sample of pure glycerol has a mass of 3.15×10^3g.

what is the density of glycerol in grams per cubic centimeter?

Explanation:

Density = unit mass/ unit volume

1L = 1000cm^3

Unit volume= 2.5 x 1000 = 2500

Unit mass = 3.15×10^3g = 3150

Density = 3150/2500 = 315/250 = 63/50 = 1 13/50 = 1.26g/cm^3

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
