The value of general gas constant 'R' for a particular gas is independant of:
Correct answer: D. Molar mass of the gas
- A. Pressure
- B. Volume
- C. Absolute temperature
- D. Molar mass of the gas
Explanation
This option is correct. The value of the gas constant 'R' is independent of the molar mass of the gas. It is the same for all gases under ideal conditions. The gas constant is usually given as 8.314 J/(mol·K) or 0.0821 L·atm/(mol·K).

About Ideal Gas Equation
The ideal gas equation, PV = nRT, relates pressure, volume, amount and absolute temperature when gas particles are assumed to have negligible volume and no intermolecular forces. Applications include finding molar mass, density or an unknown gas variable, with careful use of Kelvin temperature and consistent units, and comparison with real-gas behaviour.
