Expressed in SI units, when the universal gas constant (R) is divided by Avogadro’s number (N), we get:
Planck’s constant
Rydberg’s constant
Boltzmann’s constant
Stefan-Boltzmann constant
The value of R (Universal gas constant) in SI unit is
If the value of Avogadro number is 6.023×1023 mol−1 and the value of Boltzman constant is 1.380×10−23 J K– then the number of significant digits in the calculated value of the universal gas constant is ___
