1. What is Density?

Density is a physical property of matter defined as mass per unit volume. It's typically measured in grams per milliliter (g/mL) for liquids and solids, or grams per liter (g/L) for gases.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( \rho \) — Density (g/mL)
• \( m \) — Mass (grams)
• \( V \) — Volume (milliliters)

Explanation: This formula calculates how much mass is contained in a specific volume of a substance.

3. Importance of Density Calculation

Details: Density is a fundamental property used to identify substances, determine purity, calculate buoyancy, and solve various physics and chemistry problems.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the density of water?
A: The density of pure water at 4°C is approximately 1 g/mL, which serves as a reference point for many density measurements.

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

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

Q4: Why do some objects float while others sink?
A: Objects with lower density than the fluid they're in will float, while objects with higher density will sink.

Q5: How is density used in real-world applications?
A: Density measurements are crucial in industries like petroleum (API gravity), brewing (alcohol content), metallurgy (alloy composition), and quality control.
