IDEAL GAS LAW CONSTANT ( IDEAL GAS CONSTANT; UNIVERSAL GAS CONSTANT)

(R) A constant R equal to PV/(nT) for ideal gases , where the pressure, volume, moles, and temperature of the gas are P, V, n, and T, respectively. The value and units of R depend on the units of P, V, and T. Commonly used values and units of R include: 82.055 cm 3 atm K -1 mol -1 ; 0.082055 L atm mol -1 K -1 ; 8.31434 J mol -1 K -1 ; 1.9872 cal K -1 mol -1 ; 8314.34 L Pa mol -1 K -1 ; 8.31434 Pa m 3 mol -1 K -1 .
