  • The Density of Common Rocks and Minerals - ThoughtCo

    The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).

  • Typical Values for Rocks — Electromagnetic Geophysics

    Typical Values for Rocks ... One reason that in-situ chargeabilities tend to appear lower than laboratory values is that large volumes of mixed materials are involved in field measurements. These examples show that a wide range of variability can be expected, implying that it is difficult to use values of intrinsic chargeability (in models obtained by inversion of IP data) to determine exactly ...

  • What Are Some Reasons for Density Errors? Sciencing

    Density is mass per unit volume, so when measuring density, you find the mass of the object and divide it by its measured volume.

  • Table of Densities of Common Substances - ThoughtCo

    Here's a table of densities of common substances, including several gases, liquids, and solids.

For this reason, the table lists density from lowest to highest and includes the ...
