It is the molar equivalent to the Boltzmann constant, expressed in units of energy per temperature increment per amount of substance, rather than energy per temperature increment per particle. The constant is also a combination of the constants from Boyle's law, Charles's law, Avogadro's law, and Gay-Lussac's law.
Feb 11, 2021 · Learn the definition, value, and units of the gas constant (R), which is used in the ideal gas law and Nernst equation. Find out the difference between the universal gas constant and the specific gas constant for different gases.
R is the symbol for the gas constant, a proportionality factor that relates energy and temperature scales in several equations. The SI value of R is exactly 8.31446261815324 J⋅K −1 ⋅mol −1 , but it varies depending on the units used.

Thus, the concentration is a function of pressure and temperature, C = P RT. At 1.0 atm pressure and room temperature of 298 K, the concentration of an ideal gas is 0.041 mol/L. Avogadro's law can be further applied to correlate gas density ρ (weight per unit volume or n M / V) and molecular mass M of a gas.
The ideal gas equation enables us to examine the relationship between the non-constant properties of ideal gases ( n, P, V, T) as long as three of these properties remain fixed. For the ideal gas equation, note that the product PV is directly proportional to T.
