1. What is Density in Grams per Milliliter?

Definition: Density is a measure of mass per unit volume, typically expressed in grams per milliliter (g/mL) for liquids and small solids.

Purpose: This calculator helps determine the density of a substance by measuring its mass and volume relationship.

2. How Does the Density Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (grams per milliliter)
• \( m \) — Mass (grams)
• \( V \) — Volume (milliliters)

Explanation: The mass of the substance is divided by its volume to determine how much mass is contained in each unit of volume.

3. Importance of Density Measurement

Details: Density is a fundamental physical property used to identify substances, determine purity, and calculate buoyancy. In chemistry, it's crucial for solution preparation and material characterization.

4. Using the Calculator

Tips: Enter the mass in grams and volume in milliliters. Both values must be greater than 0. The calculator will output density in g/mL (equivalent to g/cm³).

5. Frequently Asked Questions (FAQ)

Q1: What's the density of water?
A: Pure water at 4°C has a density of exactly 1 g/mL, which serves as a reference point for other substances.

Q2: How do I measure mass and volume accurately?
A: Use a digital scale for mass and graduated cylinders or volumetric flasks for precise volume measurements.

Q3: Why does temperature affect density?
A: Most substances expand when heated (increasing volume), which decreases their density since mass stays constant.

Q4: How do I convert between g/mL and kg/m³?
A: Multiply g/mL by 1000 to get kg/m³ (1 g/mL = 1000 kg/m³).

Q5: What does it mean if my calculated density doesn't match expected values?
A: This could indicate measurement errors, impurities, or that the substance isn't what you expected.
