P V / T = R. This value is applicable for any ideal gas. According to this definition, the value of gas constant is as follows R = .082 L atm per mole per kelvin.

This constant is specific to the particular gas or mixture (hence its name), while the universal gas constant is the same for an ideal gas. Se hela listan på sciencetrends.com R is the gas constant in the ideal gas equation pV = nRT R is related to the Boltzmann constant, k, by R = k NA where k = 1.3806 x 10-23 J K-1, and N A = 6.022 x 10 23 mol-1 2019-05-28 · The specific gas constant is a version of the ideal gas constant in mass form instead of molar form. It is defined as the ratio of the ideal gas constant to the molar gas of the gas. It has the dimension of the energy per unit mass per unit absolute temperature.

where R is the universal gas constant, T the absolute temperature and RMM the relative molecular mass converson factor for the gas. In SI units R = 8314.3 J/(kmol K) and T is in K. The conversion factor RMM has the numerical value of the relative molecular mass and the units kg/kmol in the SI system. Using ideal gas equation PV = nRT R = PV/nT R =1atmp x 22.4 dm3/1 mole x 273K R = 0.0821 atmp . dm 3 /mole . In J/mole.k R is the ideal, or universal, gas constant, equal to the product of the Boltzmann constant and the Avogadro constant, In this equation the symbol R is a constant called the universal gas constant that has the same value for all gases—namely, R = 8.31 J/mol K. The power of the ideal gas law is in its simplicity.
