1. What is Density?

Density is a physical property of matter defined as mass per unit volume. It's commonly expressed in grams per milliliter (g/mL) for liquids and solids. Density helps identify substances and determine purity.

2. How Does the Calculator Work?

The calculator uses the density equation:

Where:

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

Explanation: The equation shows the direct relationship between mass and density, and the inverse relationship between volume and density.

3. Importance of Density Calculation

Details: Density measurements are crucial in chemistry, material science, and engineering. They help identify substances, determine concentrations, and design systems where buoyancy or specific gravity matters.

4. Using the Calculator

Tips: Enter mass in grams and volume in milliliters. Both values must be positive numbers. For accurate results, measure mass and volume carefully.

5. Frequently Asked Questions (FAQ)

Q1: What's the density of water?
A: Pure water has a density of approximately 1 g/mL at 4°C. This value changes slightly with temperature.

Q2: How does temperature affect density?
A: Most substances expand when heated (increasing volume), resulting in lower density at higher temperatures.

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

Q4: Can density be used to identify unknown substances?
A: Yes, density is a characteristic property that can help identify pure substances when combined with other tests.

Q5: Why do some objects float?
A: Objects float when their average density is less than the fluid they're placed in (like ships in water).
