1. What is Density of Sulfuric Acid?

Definition: Density (ρ) is the mass per unit volume of a substance. For 98% concentrated sulfuric acid (H₂SO₄), the typical density is ~1840 kg/m³.

Purpose: This calculator helps determine the density of sulfuric acid or verify the concentration based on mass and volume measurements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass of sulfuric acid is divided by its volume to calculate density.

3. Importance of Density Measurement

Details: Density is crucial for:

• Determining acid concentration
• Calculating required volumes for reactions
• Ensuring proper storage and handling
• Quality control in industrial processes

4. Using the Calculator

Tips:

• Enter the mass of sulfuric acid in kilograms
• Enter the volume in cubic meters
• For laboratory measurements, convert mL to m³ (1 mL = 0.000001 m³)
• All values must be > 0

5. Frequently Asked Questions (FAQ)

Q1: What's the density of pure sulfuric acid?
A: Pure H₂SO₄ has a density of 1830 kg/m³ at 20°C. Commercial 98% acid is ~1840 kg/m³.

Q2: How does temperature affect density?
A: Density decreases with increasing temperature (~1% decrease per 10°C temperature rise).

Q3: What density indicates 98% concentration?
A: At 20°C, 98% H₂SO₄ typically has a density of 1830-1840 kg/m³.

Q4: How do I measure mass and volume accurately?
A: Use calibrated scales for mass and graduated cylinders or volumetric flasks for volume.

Q5: What safety precautions are needed?
A: Always wear PPE (gloves, goggles, apron) when handling concentrated sulfuric acid.
