If the value of Avogadro numberis `6.023xx10^(23)mol^(-1)` and the vaueof Boltzmann constant is `1.380xx10^(-23)JK^(-1)`, then the number of significant digits in the calculated value of the universal gas constant is

If the value of Avogadro number is 6.023times10^(23)mol^(-1) and the value of Boltzmann constant is 1.380times10^(-23)JK^(-1),then the number of significant digits in the calculated value of the universal gas constant is

Why is the value of Avogadro's number 6.022 xx 10^(23) and not any other value ?

The number of significant figures in 6.02xx10^(23) is

The number of significant figures in 6.023xx10^(23) "mole"^(-1) is
