Enter the mass and volume of a crystal into the calculator to determine its density. This calculator helps in identifying the crystal by comparing the calculated density with known values.

Crystal Density Formula

The following formula is used to calculate the density of a crystal.

ρ = m / V

Variables:

  • ρ is the density of the crystal (grams per cubic centimeter)
  • m is the mass of the crystal (grams)
  • V is the volume of the crystal (cubic centimeters)

To calculate the density of a crystal, divide the mass of the crystal by its volume.

What is Crystal Density?

Crystal density is a measure of how much mass is contained in a given volume of a crystal. It is a characteristic property that can be used to identify different types of crystals. Density is particularly important in the field of mineralogy and materials science, where it can provide insights into the composition and structure of crystalline materials.

How to Calculate Crystal Density?

The following steps outline how to calculate the density of a crystal.


  1. First, measure the mass (m) of the crystal in grams.
  2. Next, measure the volume (V) of the crystal in cubic centimeters. This can be done by water displacement or other volumetric methods.
  3. Use the formula ρ = m / V to calculate the density (ρ).
  4. Finally, compare the calculated density with known densities to help identify the crystal.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Mass (m) of the crystal = 50 grams

Volume (V) of the crystal = 25 cubic centimeters
