The molar gas constant (also known as the gas constant, universal gas constant, or ideal gas constant) is denoted by the symbol R or R. It is the molar equivalent to the Boltzmann constant, expressed in units of energy per temperature increment per amount of substance, i.e. the pressure–volume product, rather … See more From the ideal gas law PV = nRT we get: $${\displaystyle R={\frac {PV}{nT}}}$$ where P is pressure, V is volume, n is number of moles of a given substance, and T is temperature. As pressure is … See more The specific gas constant of a gas or a mixture of gases (Rspecific) is given by the molar gas constant divided by the molar mass (M) … See more The U.S. Standard Atmosphere, 1976 (USSA1976) defines the gas constant R as: R = 8.31432×10 N⋅m⋅kmol ⋅K = 8.31432 J⋅K ⋅mol . Note the use of kilomoles, with the resulting factor of … See more The Boltzmann constant kB (alternatively k) may be used in place of the molar gas constant by working in pure particle count, N, rather than amount of substance, n, since See more As of 2006, the most precise measurement of R had been obtained by measuring the speed of sound ca(P, T) in argon at the temperature T of the triple point of water at different pressures P, and extrapolating to the zero-pressure limit ca(0, T).
