The value of R (the gas constant) is:
Correct answer: C. 0.0821 dm3 atm k-I mol-1
- A. 0.0821dm3 atm k mol-1.
- B. 803143 Nmk-Imole
- C. 0.0821 dm3 atm k-I mol-1
- D. 8.3143 dm3 atm k-I mol
Explanation
The value of R is different for different units of volume and pressure.

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.
