Density

Density of Rocks. Bulk density of rocks follows exactly Eq. (4.2) and depends on: (1) the mineral composition (mineral densities and volume fractions), and (2) porosity (pores, fractures) and density of pore fluids. This explains the general rule of density variation: • igneous rocks show an increase of density from felsic (acid) to …

2: The Density of Liquids and Solids (Experiment)

Since pure substances have unique density values, measuring the density of a substance can help identify that substance. Density is determined by dividing the mass of a substance by its volume: [Density = frac{Mass}{Volume}] The units of density are commonly expressed as g/cm 3 for solids, g/mL for liquids, and g/L for gases.

Density: Accuracy and Precision

Accuracy is a measure of how close your measured value is to the correct value. For example, if a substance has a density of 1.23 g/mL and you measure its density to be 1.24 g/mL, then you were accurate. The difference between the experimentally measured value and the accepted value is very small.

Clays generally have density between 1.6 to 2.6 g/cc. The clay content of a soil has a significant effect on its density. Salt is of particular interest in sedimentary rocks because it has a low density (2.2 g/cc), but has a fairly high bulk modulus giving it a relatively high seismic velocity (velocity of acoustic signals within the rock).
