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

If the value of Avogadro number is 6.023 xx 10^23 mol^(-1) and the value of Boltzmann constant is 1.380 xx 10 ^(-23) J K^(-1) , then the number of significant digits in the calculated value of the universal gas constant is

If the value of Avogadro number is 6.023 xx 10^23 "mol"^(-1) and the value of Boltzmann constant is 1.380 xx 10^(-23) JK^(-1) , then the number of significant digits in the calculated value of the universal gas constant is [Hint: Since k and N, both have four significant figures, the value of R is also rounded off up to four significant figures.]

Avogadro's number is 6.023xx 10 ^(-23) .

Why is the value of Avogadro's number 6.022xx10 ^(23) and not any other value ?
