Avogadro's Number

The Avogadro constant ($N_A$ or $L$) is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one Mole. It is exactly $6.02214076\times 10^{23}$ per mole.

Essentially, the number of elements required to reach its Atomic Weight in grams (e.g. $N_A$ Lithium atoms will have a mass of ~6.94g).

Value

$N_A=6.02214076\times 10^{23}{\text{mol}}^{-1}$

Symbol(s)
