value of r in pv nrt
The units of the universal gas constant R is derived from equation PV=nRT. It stands for Regnault. then R is in Lâatm/molâK. R has the value 0.082057 Lâatm/molâK with the above units for the remaining variables. In other scenarios with pressures of bars instead, you may also use 0.083145 Lâbar/molâK.
