Specific Gas Constant Calculator
Calculate Rs for a gas using molar mass.
Instructions
Enter the gas molar mass in g/mol. The calculator converts to kg/mol and computes Rs = R / M.
Formula
Rs = R / M
R = 8.314 J/mol·K, M in kg/mol.
About Specific Gas Constant
The specific gas constant relates pressure, density, and temperature via ideal gas law: p = ρ Rs T.
Common Questions
How do I get molar mass?
Sum atomic masses from the chemical formula or look up standard values.
Is this for ideal gases?
Yes. For real gases, corrections may be needed at high pressures.
