Answer to Question #22533 in Inorganic Chemistry for ADNAN

Question #22533
If the atomic weight of carbon were set at 24 amu, the value of the Avogadro constant
would be?
Expert's answer
The Avogadro constant enters into the definition ofthe unified atomic mass unit, u,

1 u = Mu / Na = 1,6605 * 10^-24

where Mu is the molar mass constant and Na is Avogadro constant.

Mu = Mw / Ar

If Mw= 24 amu

Mu = 24 amu / 12 = 2

Na' = Mu / 1,6605 * 10^-24 = 2 / 1,6605 * 10^-24 = 1,2
* 10^24

This is " new" Avogadro constant = 1,2 * 10^24
