The gas constant occurs in the ideal gas law: where P is the absolute pressure, V is the volume of gas, n is the amount of substance, m is the mass, and T is the thermodynamic temperature. Rspecific is the mass-specific gas constant. The gas constant is expressed in the same unit as molar heat.
The gas constant R is 8.314 J / mol·K. Convert the numerical value of R so that its units are cal / (mol·K). A unit conversion table will tell you that 1 cal = 4.184 J. Make sure you know where to find it.
R = Universal gas constant (J/mol.K, lit.atm/mol.K) T = Temperature of the gas (K, 0 C) "R" is also known by alternative names such as Ideal gas constant, molar gas constant or simply, R gas constant.
In the imperial system the most common units for the individual gas constant are ft lb/slug o R . In the SI system the most common units are J/kg K . Unit conversion: 1 J/kg K = 5.97994 ft lb/slug °R, and 1 ft lb/slug °R = 0.167226 J/kg K.
The gas constant (R) is a proportionality constant used in the ideal gas law and Nernst equation. It’s also called the ideal gas constant, universal gas constant, or molar gas constant. Basically, the gas constant is the same as the Boltzmann constant (k), except the gas constant includes Avogadro’s number (N A): R = NA k.
Since there is Avogadro’s number of molecules per mole, we can divide any of the values above by \(\overline{N}\) to get \(R\) on a per-molecule basis. Traditionally, however, this constant is given a different name; it is Boltzmann’s constant, usually given the symbol \(k\).
The gas constant is a physical constant denoted by R and is expressed in terms of units of energy per temperature increment per mole. It is also known as the ideal gas constant or molar gas constant or universal gas constant.
The proportionality constant, R, is called the gas constant and has the value 0.08206 (L·atm)/(K·mol), 8.3145 J/(K·mol), or 1.9872 cal/(K·mol), depending on the units used.
Calculate any variable in the equation for the Ideal Gas Law PV = nRT, where pressure times volume equals moles times the ideal gas constant times temperature.
Ideal gas constant. The ideal gas constant is also known as the molar gas constant, the gas constant or the universal gas constant. This constant is written as R R, and is a constant of proportionality (constant number that is multiplied on one side of a proportional relationship to make them equal) for the ideal gas law. [1]
