The equation of state for $\mathrm{n}$ moles of an ideal gas is $\mathrm{PV}=\mathrm{nRT}$, where $\mathrm{R}$ is a constant. The SI unit for $\mathrm{R}$ is

• A

  $\mathrm{JK}^{-1}$ per molecule
• Correct answer
  B

  $\mathrm{JK}^{-1} \mathrm{~mol}^{-1}$
• C

  $\mathrm{J} \mathrm{Kg}^{-1} \mathrm{~K}^{-1}$
• D

  $\mathrm{JK}^{-1} \mathrm{~g}^{-1}$

Hence, the correct answer is option: 'B'.
