The correct value of the general gas constant R is:
Correct answer: D. 8.314 x 10^7erg mol-1K-1
- A. 8.314 atm dm3 mol K-1
- B. 0.0821 Jmol-1 K-1
- C. 62.4 torr cm3 mol-1K-1
- D. 8.314 x 10^7erg mol-1K-1
Explanation
R=8.3143 Nm.mol-1.K-1 1Nm=107erg Hence,8.3143*107erg.mol-1K-1

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.
