1. What is Carbon Monoxide Density Calculator?

Definition: This calculator estimates the density of carbon monoxide gas based on pressure and temperature using the ideal gas law.

Purpose: It helps engineers, chemists, and safety professionals determine CO gas density for various applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \rho = \frac{P \times M}{R \times T} \]

Where:

\( \rho \) — Density of CO (kg/m³)
\( P \) — Pressure (Pascals)
\( M \) — Molar mass of CO (0.028 kg/mol)
\( R \) — Universal gas constant (8.314 J/(mol·K))
\( T \) — Temperature (Kelvin)

Explanation: The formula is derived from the ideal gas law, relating gas density to its pressure and temperature.

3. Importance of CO Density Calculation

Details: Knowing CO density is crucial for ventilation design, gas detection systems, and industrial process calculations.

4. Using the Calculator

Tips: Enter pressure in Pascals (default 101325 Pa = 1 atm) and temperature in Kelvin (default 273.15 K = 0°C). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the density of CO at STP?
A: At standard temperature and pressure (0°C, 1 atm), CO density is approximately 1.25 kg/m³.

Q2: How does temperature affect CO density?
A: Density decreases as temperature increases (inverse relationship), assuming constant pressure.

Q3: How does pressure affect CO density?
A: Density increases linearly with increasing pressure at constant temperature.

Q4: Why is molar mass fixed at 0.028 kg/mol?
A: This is the molecular weight of CO (12 for C + 16 for O = 28 g/mol = 0.028 kg/mol).

Q5: Is this calculation accurate for high pressures?
A: The ideal gas law becomes less accurate at very high pressures; real gas equations would be needed.
