Rock Density Formula:
| From: | To: |
Rock density is a fundamental physical property that measures the mass per unit volume of a rock sample. It is expressed in grams per cubic centimeter (g/cm³) and helps in identifying rock types and understanding their composition.
The calculator uses the rock density formula:
Where:
Explanation: The formula calculates density by dividing the mass of the rock by its volume, providing a measure of how much mass is contained in a given volume.
Details: Calculating rock density is essential in geology, civil engineering, and mining. It helps in rock identification, assessing material strength, and determining suitability for construction and other applications.
Tips: Enter the mass in grams and volume in cubic centimeters. Both values must be positive numbers. The calculator will compute the density in g/cm³.
Q1: Why is rock density important?
A: Rock density helps in identifying rock types, understanding their composition, and assessing their suitability for various engineering and construction purposes.
Q2: What are typical density values for common rocks?
A: Common rock densities range from about 2.0 g/cm³ for sedimentary rocks like sandstone to 3.0 g/cm³ or more for igneous rocks like basalt.
Q3: How is volume measured for irregularly shaped rocks?
A: For irregular shapes, volume can be measured using water displacement method where the rock is submerged in water, and the volume of displaced water is measured.
Q4: Can this calculator be used for other materials?
A: Yes, the same formula applies to any solid material, though the units should be consistent (mass in grams, volume in cm³ for density in g/cm³).
Q5: What factors affect rock density?
A: Rock density is affected by mineral composition, porosity, and the presence of voids or fractures within the rock.
