What is the value of universal gas constant in S.I. units?
Correct answer: A. 8.314 Jmol-1K-1
- A. 8.314 Jmol-1K-1
- B. 8.314 dm 3atm mol-IK-I
- C. 0.0821 dm3atm mol-I K-1
- D. 0.0821 Jmol-1K-1
Explanation
a) 8.314 J mol^(-1) K^(-1)Explanation: This option suggests that the value of the universal gas constant in SI units is 8.314 J mol^(-1) K^(-1). This is the correct value of the universal gas constant in SI units. It is used when working with SI units in thermodynamic calculations.

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.
