1. What is Ethane Density Calculator?

Definition: This calculator computes the density of ethane gas using the ideal gas law.

Purpose: It helps chemists, engineers, and students determine ethane's density under various conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( P \) — Pressure (Pascals)
• \( M \) — Molar mass of ethane (0.030 kg/mol)
• \( R \) — Universal gas constant (8.314 J/(mol·K))
• \( T \) — Temperature (Kelvin)

Explanation: The formula relates gas density to its pressure, molar mass, and temperature.

3. Importance of Ethane Density Calculation

Details: Knowing ethane's density is crucial for storage, transportation, and industrial processes in petrochemical industries.

4. Using the Calculator

Tips: Enter pressure (default 101325 Pa for STP), temperature (default 273.15 K for 0°C), and molar mass (default 0.030 kg/mol for ethane).

5. Frequently Asked Questions (FAQ)

Q1: What's ethane's density at STP?
A: At standard temperature and pressure (0°C, 1 atm), ethane's density is approximately 1.34 kg/m³.

Q2: How does temperature affect ethane density?
A: Density decreases as temperature increases (inverse relationship).

Q3: How does pressure affect ethane density?
A: Density increases with increasing pressure (direct relationship).

Q4: Is this calculation accurate for real gases?
A: It's most accurate for ideal gas behavior. For precise calculations at high pressures or low temperatures, use more complex equations of state.

Q5: What are common uses of ethane?
A: Ethane is primarily used as a petrochemical feedstock for ethylene production and as a refrigerant.
