1. What is Density?

Density is a physical property of matter defined as mass per unit volume. It is a fundamental concept in physics and chemistry that helps characterize materials and substances.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( D \) — Density (g/mL)
• \( m \) — Mass (g)
• \( V \) — Volume (mL)

Explanation: The formula calculates how much mass is contained in a given volume of a substance.

3. Importance of Density Calculation

Details: Density calculations are essential for material identification, quality control, buoyancy calculations, and various scientific and industrial applications.

4. Using the Calculator

Tips: Enter mass in grams and volume in milliliters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What are common units for density?
A: Common units include g/mL, g/cm³, kg/m³. 1 g/mL = 1 g/cm³ = 1000 kg/m³.

Q2: Why does density vary between materials?
A: Density depends on atomic/molecular mass and how closely particles are packed together in the material.

Q3: How does temperature affect density?
A: Most substances expand when heated, increasing volume and decreasing density. Water is an exception between 0-4°C.

Q4: What is the density of water?
A: Pure water has a density of approximately 1 g/mL at 4°C.

Q5: How is density used in real-world applications?
A: Density is used in material identification, quality control, buoyancy calculations, and determining concentration in solutions.
