R constant is
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 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 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 . 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 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 • Ideal gas calculator Archived 2012-07-15 at the Wayback Machine – Ideal gas calculator provides the correct information for the moles of gas involved. • Individual Gas Constants and the Universal Gas Constant See more
