State whether the following statement is true or false:
$A$ mole always represents $6.023 \times 10^{22}$ atoms,molecules,or ions of a substance.
$A$ mole always represents $6.023 \times 10^{22}$ atoms,molecules,or ions of a substance.
(B) The statement is False.
Explanation: $A$ mole of any substance is defined as the amount of substance that contains exactly $6.02214076 \times 10^{23}$ elementary entities (atoms,molecules,or ions). This constant is known as Avogadro's number $(N_A)$. The value provided in the statement,$6.023 \times 10^{22}$,is incorrect by a factor of $10$.
