1. What is Liquid Density?

Density is a physical property of matter defined as mass per unit volume. For liquids, it's typically measured in grams per milliliter (g/mL) or kilograms per liter (kg/L). Density helps identify substances and predict their behavior in different environments.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

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

Explanation: This formula calculates how much mass is contained in a given volume of liquid, providing its density.

3. Importance of Density Calculation

Details: Density measurement is crucial in various fields including chemistry, engineering, and food science. It helps identify substances, determine purity, and calculate concentrations in solutions.

4. Using the Calculator

Tips: Enter mass in grams and volume in milliliters. Ensure both values are positive numbers greater than zero for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard unit for liquid density?
A: The most common units are g/mL or kg/L. 1 g/mL equals 1000 kg/m³ in SI units.

Q2: How does temperature affect liquid density?
A: Most liquids expand when heated, causing density to decrease as temperature increases. Water is an exception between 0-4°C.

Q3: What is the density of pure water?
A: Pure water has a density of approximately 1 g/mL at 4°C, which is often used as a reference point.

Q4: How can density identify unknown liquids?
A: Different liquids have characteristic densities. Measuring density can help identify an unknown liquid or detect impurities.

Q5: Why do some liquids float on others?
A: Liquids with lower density will float on liquids with higher density. This principle is used in various separation techniques.
