Respuesta :

 She must use Avogadro's Number. Avogadro's number is the number of molecules in a mole of a substance, so if you have 12.4 moles of something, then you have 12.4 times Avogadro's number of molecules.

Answer:

Avogadro's number is used.

Explanation:

To know the number of molecules of any compound and the number of moles is known, the most ideal is to use the Avogadro number, which is defined as 6.022x10^23 molecules on one mole of any compound. If we do the conversion with the number of moles, we will obtain the number of molecules of the compound that we want.
