(physics) a universal constant, R, that appears in the ideal gas law, (PV = nRT), derived from two fundamental constants, the Boltzman constant and Avogadro's 

R = universal gas constant = 8.3145 J/mol K N = number of molecules k = Boltzmann constant = 1.38066 x 10-23 J/K = 8.617385 x 10-5 eV/K k = R/N A; N A = Avogadro's number = 6.0221 x 10 23 /mol The ideal gas law can be viewed as arising from the kinetic pressure of gas

The ideal gas law is the equation of state of an ideal gas. It relates the state variables of the gas: pressure (P), (P), (P), volume (V), (V), (V), and temperature (T).

(R=8.314 \frac{\text{J}}{\text{K mol}}). (R = 8. 3 1 4 K mol J R is defined as the universal gas constant divided by the molecular weight of the substance, i.e. The dimensions of R are not the same as those of R u, since molecular weight is a not a dimensionless quantity, although some authors treat it as such. The ideal gas law in terms of R is where P is the absolute pressure of the gas, V is the volume A and R* is the ideal gas constant = k B N A. So the macroscopic version of the ideal gas law is P = N R* T where P is pressure in pascals, n is the number density of the gas in molecules per unit volume and T is the temperature in Kelvin and R* is the gas constant = 8.314472 in J/K/mol. Notice: mass does not enter the ideal gas law equation.

Definitions of the important terms you need to know about in order to understand Ideal Gases, including Absolute temperature , Absolute zero , Avogadro's law , Avogadro's number , Boyle's law , Charles' law , Dalton's law , Gas constant , Ideal gas law , Isothermal conditions , Kelvin , Manometer , Molar mass , Mole , Mole fraction , Partial pressure , Standard atmospheric temperature and R, here is a proportionality constant. Therefore we can write, P V = n R T or R = PV/nT.

The gas constant (symbol R) is also called the molar or universal constant. It is used in many fundamental equations, such as the ideal gas law. The value of this constant is 8.3144626 J/ (mol·K).

Quinn, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 III.B.1 Gas Thermometry. The ideal-gas law [Eq.(5)] is valid experimentally for a real gas only in the low-pressure limit, with higher-order terms (the virial coefficients, not defined here) effectively causing R to be both pressure and temperature dependent for most experimental conditions.
