The value of the universal constant "R" is:
Correct answer: D. 8.314 J mole-1 K-1
- A. 8.314 J mol-3K-3
- B. 1.38J mole-1 K-3
- C. 1.38J mole-1 K-1
- D. 8.314 J mole-1 K-1
Explanation
Physically, the gas constant is the constant of proportionality that relates the energy scale in physics to the temperature scale, when a mole of particles at the stated temperature is being considered. The value of R is 8.314J K−1mol−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.
