Density is a measure of how compact a material is. The greater the density, the more mass is squeezed into a particular volume. Mathematically, density is expressed as the ratio of mass to volume. Duration: 8:06.
Molecular Polarity and Nonpolarity
C0608Na
Determining whether a molecule is polar or nonpolar requires a careful study of the geometry of the molecule. In some instances, would-be dipoles balance each other out to make the molecule, as a whole, nonpolar. Duration: 7:04
