1. What is Density?

Density is a physical property of matter defined as mass per unit volume. It's an intensive property, meaning it doesn't depend on the amount of material. The standard units are g/mL or kg/L for liquids.

2. How Does the Calculator Work?

The calculator uses the basic density formula:

Where:

• Mass — Weight of the substance (g or kg)
• Volume — Space occupied by the substance (mL or L)
• Density — Resulting density (g/mL or kg/L)

Explanation: The calculator automatically handles unit conversions between different mass and volume units.

3. Importance of Density Calculation

Details: Density measurements are crucial in chemistry, physics, engineering, and many industrial applications. It helps identify substances, determine purity, and calculate buoyancy.

4. Using the Calculator

Tips: Enter mass (must be > 0), volume (must be > 0), and select appropriate units. The calculator will automatically determine the correct output unit based on your inputs.

5. Frequently Asked Questions (FAQ)

Q1: What's the density of water?
A: Pure water at 4°C has a density of 1.000 g/mL or 1000 kg/m³. At room temperature, it's about 0.997 g/mL.

Q2: How does temperature affect density?
A: Most substances expand when heated (lower density) and contract when cooled (higher density). Water is an exception between 0-4°C.

Q3: What's the difference between mass and density?
A: Mass is the amount of matter, while density is how tightly that matter is packed into a given volume.

Q4: Can this calculator be used for gases?
A: The formula works, but gas densities are typically much lower and more temperature/pressure sensitive than liquids.

Q5: How precise should my measurements be?
A: For accurate results, measure mass to at least 0.01g and volume to 0.1mL when possible.
