1. What is Basalt Density?

Definition: Basalt is a common extrusive igneous rock with a density typically ranging between 2.8-3.0 g/cm³ (average ~2.7 g/cm³).

Purpose: Knowing basalt density is important for construction, geology, and engineering applications where weight and volume calculations are needed.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density in g/cm³
• \( \rho_{kg/m³} \) — Density in kg/m³

Explanation: The conversion simply divides the kg/m³ value by 1000 to convert to g/cm³ since 1 g/cm³ = 1000 kg/m³.

3. Importance of Basalt Density

Details: Basalt density affects structural calculations, buoyancy assessments, and material selection in construction and manufacturing.

4. Using the Calculator

Tips: Enter the basalt density in kg/m³ (default 2700 kg/m³ for average basalt). The calculator converts this to g/cm³.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density range for basalt?
A: Basalt typically ranges from 2.8-3.0 g/cm³ (2800-3000 kg/m³), with an average of about 2.7 g/cm³ (2700 kg/m³).

Q2: Why are there different density values for basalt?
A: Density varies based on mineral composition, porosity, and vesicularity (gas bubble content).

Q3: How does basalt density compare to other rocks?
A: Basalt is denser than granite (~2.6-2.7 g/cm³) but less dense than peridotite (~3.3 g/cm³).

Q4: When would I need to know basalt density?
A: Important for construction projects, road building, aggregate calculations, and geological studies.

Q5: Does vesicular basalt have different density?
A: Yes, vesicular (porous) basalt can have significantly lower density due to air pockets.
