WebThe universal gas constant(Ru) is, as its name implies, universal, i.e., the same regardless of the gas being considered. The ideal gas lawin terms of Ruis PnRTV u, where Pis the absolute pressure of the gas, Vis the volume occupied by the gas, nis the number of mols of the gas, and Tis the absolute temperature of the gas. In case of air, using the perfect gas law and the standard sea-level conditions (SSL) (air density ρ0 = 1.225 kg/m 3, temperature T0 = 288.15 K and pressure p0 = 101 325 Pa ), we have that Rair = P0 / ( ρ0T0) = 287.052 874 247 J·kg−1·K−1. Then the molar mass of air is computed by M0 = R / Rair = 28.964 917 g/mol. [11] See more 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 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 … 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) of the gas or mixture. $${\displaystyle R_{\rm {specific}}={\frac {R}{M}}}$$ Just as the molar … 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 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 $${\displaystyle R=N_{\rm {A}}k_{\rm {B}},\,}$$ 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 .
