Universal Gas Constant (R)
* Represents the relationship between the energy, volume, temperature, and number of moles of an ideal gas.
* Value: 8.314 J/mol·K
* Units: Joules per mole per Kelvin (J/mol·K)
Avogadro's Constant (NA)
* Represents the number of atoms or molecules in one mole of a substance.
* Value: 6.022 x 1023 mol-1
* Units: Per mole (mol-1)
Relationship between R and NA:
The universal gas constant (R) can be expressed as the product of Boltzmann's constant (kB) and Avogadro's constant (NA):
R = kB * NA
where:
* kB = Boltzmann's constant = 1.38 x 10-23 J/K
In summary:
While they are related through Boltzmann's constant, the universal gas constant (R) and Avogadro's constant (NA) represent distinct physical quantities and have different units. R relates energy, volume, temperature, and moles in ideal gases, while NA defines the number of particles in a mole.
