Question

select true or false: the definition of a mole is an avogadros number of a specific entity, such as an atom or molecule. true false

Explanation:

A mole is defined as the amount of substance that contains as many elementary entities (such as atoms, molecules, ions, etc.) as there are atoms in exactly 12 grams of carbon - 12. Avogadro's number ($N_A\approx6.022\times 10^{23}$) is the number of these entities in one mole. So the statement "The definition of a mole is an Avogadro's number of a specific entity, such as an atom or molecule" is a correct way to understand the mole concept (in a simplified sense for basic understanding).

Answer:

true
