What is the value of R for an ideal gas?
= 8.314 J/mol
The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K.
What is K in the ideal gas constant?
The ideal gas law can be written in terms of the number of molecules of gas: PV = NkT, where P is pressure, V is volume, T is temperature, N is number of molecules, and k is the Boltzmann constant k = 1.38 × 10–23 J/K.
What is R in PV RT?
In the equation PV=nRT, the term “R” stands for the universal gas constant. The universal gas constant is a constant of proportionality that relates the energy of a sample of gas to the temperature and molarity of the gas. It is sometimes called the ideal gas constant, the molar gas constant.
What is N in ideal gas equation?
n = number of moles (mol) R = the Ideal Gas Law Constant. T = Temperature in Kelvin (K) The value n is the amount of the gas measured as moles. One may need to convert a mass to moles by dividing the given mass of the gas by the molar mass of the gas to get moles.
What unit is V in PV nRT?
The units used in the ideal gas equation that PV = nRT are: P is pressure measured in Pascals. V is the volume measured in m. n is the number of moles.
What does N PV RT stand for?
n. A physical law describing the relationship of the measurable properties of an ideal gas, where P (pressure) × V (volume) = n (number of moles) × R (the gas constant) × T (temperature in Kelvin). It is derived from a combination of the gas laws of Boyle, Charles, and Avogadro. Also called universal gas law.

What is the specific gas constant in chemistry?
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. The SI unit is J kg −1 K −1.
What is the idideal gas constant?
Ideal Gas Constant: Definition, Values, and Units. The ideal gas constant is also known as the universal gas constant or the molar gas constant or simply the gas constant. It is a very important constant in chemistry and physics. It is denoted as \\(R\\). The dimension of the gas constant is expressed in energy per unit mole per unit temperature.
What is the formula for the universal gas constant?
The Universal Gas Constant (R*) is common to all gases and its value is dependent on the units use to describe the rest of the ideal gas law equation. In SI units, the universal gas constant value is R* = 8.314462175 J / mol.K. Table of universal gas constant in different units: Individual Gas Constant Ri.
