1. What is Density of Oxygen Gas in g/L?

Definition: This calculator converts the density of oxygen gas from kg/m³ to g/L.

Purpose: It helps scientists, engineers, and students work with oxygen gas density in different unit systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density in g/L
• \( \rho_{kg/m³} \) — Density in kg/m³

Explanation: Since 1 kg/m³ equals 1 g/L, the conversion is straightforward. The default value of 1.429 kg/m³ represents oxygen gas density at standard temperature and pressure (STP).

3. Importance of Oxygen Density Calculation

Details: Knowing oxygen density is crucial for chemical engineering, medical applications, combustion calculations, and various industrial processes.

4. Using the Calculator

Tips: Enter the oxygen density in kg/m³ (default 1.429 kg/m³ for STP). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the density of oxygen at STP?
A: At standard temperature and pressure (0°C, 1 atm), oxygen has a density of approximately 1.429 g/L (or 1.429 kg/m³).

Q2: How does temperature affect oxygen density?
A: Density decreases with increasing temperature (Charles' Law) and increases with pressure (Boyle's Law).

Q3: Why use g/L instead of kg/m³?
A: g/L is often more convenient for gas measurements in laboratory settings where volumes are typically in liters.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact since 1 kg/m³ = 1 g/L by definition.

Q5: What's the density of oxygen at room temperature?
A: At 20°C and 1 atm, oxygen density is about 1.331 g/L (lower than at STP due to thermal expansion).
