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. Different substances have characteristic densities that can be used for identification.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• Mass — Measured in grams (g) or kilograms (kg)
• Volume — Measured in milliliters (mL) or liters (L)
• Density — Result in g/mL or kg/L depending on input units

Explanation: The calculator automatically handles unit conversions to provide consistent results.

3. Importance of Density Measurement

Details: Density measurements are crucial in chemistry, material science, and engineering for identifying substances, determining purity, and calculating buoyancy forces.

4. Using the Calculator

Tips: Measure the mass of your liquid using a scale and its volume using a graduated cylinder. Enter the values with appropriate units. For best accuracy, measure at standard temperature (usually 20°C).

5. Frequently Asked Questions (FAQ)

Q1: What's the density of water?
A: Pure water has a density of 1.000 g/mL at 4°C (0.9998 g/mL at 20°C).

Q2: How does temperature affect density?
A: Most substances expand when heated (lower density) and contract when cooled (higher density), with water being a notable exception between 0-4°C.

Q3: What's the difference between g/mL and kg/L?
A: They're numerically equivalent (1 g/mL = 1 kg/L) but represent different scales of measurement.

Q4: How accurate is this calculation?
A: Accuracy depends on the precision of your mass and volume measurements. Use calibrated equipment for best results.

Q5: Can this be used for gases?
A: The same formula applies, but gas densities are highly temperature/pressure dependent and typically much lower than liquids.
