Description : Chemistry formula PV = nRT, here , what is the meaning of R ?
Last Answer : Here R is the molar gas constant. The value of R is L-atm unit 0.0621 L atm mol-¹K- . The dimension of R = work / (mole × K) Thus , the amount of work or energy obtained from the standard gas per mole for 1 K temperature increase is equal to R. This is the physical significance of R.
