1. What is the Density Formula?

The density formula calculates the mass per unit volume of a substance. It is expressed as D = m/V, where D is density, m is mass, and V is volume. Density is typically measured in grams per milliliter (g/mL) for liquids and small solids.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

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

Explanation: The formula calculates how much mass is contained in a given volume of a substance.

3. Importance of Density Calculation

Details: Density is a fundamental physical property used to identify substances, determine purity, and calculate buoyancy. It's crucial in fields like chemistry, physics, engineering, and materials science.

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 are common units for density?
A: While g/mL is common for liquids and small solids, density can also be expressed in kg/m³, lb/ft³, or other mass/volume units depending on the context.

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

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

Q4: How is density used to identify substances?
A: Each pure substance has a characteristic density, so measuring density can help identify unknown materials or detect impurities.

Q5: Can density be used to determine if an object will float?
A: Yes, objects with density less than the fluid they're placed in will float, while those with greater density will sink.
