1. What is Density?

Density is a physical property of matter defined as mass per unit volume. In the metric system, it is commonly measured in grams per cubic centimeter (g/cm³) and represents how much mass is contained in a given volume of a substance.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( \rho \) — Density (g/cm³)
• \( m \) — Mass (grams)
• \( V \) — Volume (cubic centimeters)

Explanation: The formula calculates how densely packed the mass is within a given volume. Higher density values indicate more mass concentrated in the same volume.

3. Importance of Density Calculation

Details: Density is crucial in material science, engineering, chemistry, and physics. It helps identify substances, determine purity, calculate buoyancy, and design materials for specific applications.

4. Using the Calculator

Tips: Enter mass in grams and volume in cubic centimeters. Ensure both values are positive numbers. The calculator will compute the density in g/cm³ with four decimal precision.

5. Frequently Asked Questions (FAQ)

Q1: What is the density of water?
A: Pure water has a density of approximately 1 g/cm³ at 4°C, which serves as a reference point for many density measurements.

Q2: How does temperature affect density?
A: Most substances expand when heated, increasing volume while mass remains constant, resulting in decreased density. Water is an exception between 0-4°C.

Q3: What are common density units?
A: Common units include g/cm³, kg/m³ (1000 kg/m³ = 1 g/cm³), and lb/ft³ for imperial measurements.

Q4: Why is density important in everyday life?
A: Density explains why objects float or sink, helps in cooking measurements, and is used in manufacturing and quality control of materials.

Q5: Can density be used to identify materials?
A: Yes, each pure substance has a characteristic density that can help identify it, though additional tests are usually needed for confirmation.
