1. What is Density?

Density is a physical property of matter defined as mass per unit volume. It is commonly expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( D \) — Density (g/cm³)
• \( m \) — Mass (g)
• \( V \) — Volume (cm³)

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

3. Importance of Density Calculation

Details: Density is a fundamental property used to identify substances, determine purity, and calculate buoyancy. It's essential in various fields including physics, chemistry, engineering, and materials science.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are common density values?
A: Water has a density of 1 g/cm³. Most metals have higher densities (e.g., iron: 7.87 g/cm³), while gases have much lower densities.

Q2: How does temperature affect density?
A: Density generally decreases with increasing temperature for most substances, as thermal expansion causes volume to increase while mass remains constant.

Q3: What is the difference between density and specific gravity?
A: Specific gravity is the ratio of a substance's density to the density of water at 4°C, making it a dimensionless quantity.

Q4: Can density be used to identify unknown substances?
A: Yes, density is a characteristic property that can help identify pure substances, though additional tests are usually needed for confirmation.

Q5: How is density measured experimentally?
A: Common methods include using a balance to measure mass and graduated cylinder to measure volume, or using a density bottle for more precise measurements.
