1. What is CO2 Density Conversion?

Definition: This calculator converts the density of carbon dioxide (CO₂) from kilograms per cubic meter (kg/m³) to grams per liter (g/L).

Purpose: It helps scientists, engineers, and students working with CO₂ gas to convert between these common density units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density in grams per liter (g/L)
• \( \rho_{kg/m³} \) — Density in kilograms per cubic meter (kg/m³)

Explanation: Since 1 kg/m³ equals 0.001 g/L, we divide the kg/m³ value by 1000 to get g/L.

3. Importance of CO₂ Density

Details: CO₂ density is crucial for various applications including carbon capture, beverage carbonation, fire suppression systems, and climate science.

4. Using the Calculator

Tips: Enter the CO₂ density in kg/m³ (default 1.98 kg/m³ at STP). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the density of CO₂ at standard conditions?
A: At STP (0°C, 1 atm), CO₂ has a density of about 1.98 g/L or 1.98 kg/m³.

Q2: Why convert between these units?
A: g/L is more convenient for small-scale lab work, while kg/m³ is standard in engineering calculations.

Q3: How does temperature affect CO₂ density?
A: Density decreases with increasing temperature at constant pressure (following the ideal gas law).

Q4: What's the density of liquid CO₂?
A: Liquid CO₂ at 20°C is much denser - about 770 kg/m³ or 0.770 g/mL.

Q5: How accurate is this conversion?
A: The conversion is mathematically exact, but actual CO₂ density varies with temperature and pressure.
