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

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

(a) Why does not the atomic mass of an element represent the actual mass of its atom? (b) The atomic mass of an element is in fraction. What does it mean? (c) Why is the value of Avogadros number 6.022 xx 10^(23) and not any other value? (d Does one gram mole of a gas occupy 24.4 L under all conditions of temperature and pressure?

The value of avagadros number is 6.022xx10^(23) .

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

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

Mole concept is an important tool for dealing with chemical calculations. The element have atomic mases while compounds have molecular masses or molar masses. Mole is infact, a collection of Avogadro's number (N_(A)) of the particles of a substance whether element or compound. The value of Avogadro's number is 6.022 xx 10^(23) (a) Why is mole commonly called chemist's dozen ? (b) What is the value associated with the term mole ?

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 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
