Specific Gas Constant Calculator

How to Use This Calculator

1. Enter the molar mass of the gas in g/mol. This is the mass of one mole of the gas.
2. Select the unit for the universal gas constant that you prefer (J/(mol·K), L·atm/(mol·K), or cal/(mol·K)).
3. Click the "Calculate" button to compute the specific gas constant.
4. The result will be displayed in the same unit as the universal gas constant.

What is the Specific Gas Constant?

The specific gas constant (R_s) is a characteristic of a particular gas that relates its pressure, volume, and temperature to the amount of gas. It is calculated by dividing the universal gas constant (R) by the molar mass (M) of the gas.

Applications

The specific gas constant is used in various thermodynamic calculations involving gases, including:

• Calculating the pressure of a gas given its volume, temperature, and amount
• Determining the volume of a gas at a given pressure and temperature
• Understanding the behavior of real gases in various conditions

Formula

R_s = R / M

Where:

• R_s = Specific gas constant (J/(kg·K), L·atm/(kg·K), etc.)
• R = Universal gas constant (8.314 J/(mol·K), 0.0821 L·atm/(mol·K), etc.)
• M = Molar mass of the gas (g/mol)
