  1. Para mostrar esquemáticamente toda la información asociada al concepto de mol, tomamos como ejemplo el etanol, C2H6O, que es el alcohol más utilizado en aplicaciones domésticas: Masas atómicas: M (C) = 12 u; M (H) = 1 u; M (O) = 16 u Masa molecular (C2H6O) = 2 · 12 + 6 · 1 + 16 = 46 u 6,022 · 1023 moléculas de C2H6O 1 · 46 = 46 g de C2H6O 2 moles de átomos de C 1,204 · 1024 átomos de C 2 · 12 = 24 g de C 1 mol de C2H6O 3,613 · 1024 átomos de H 6 moles de átomos de H 6 · 1 = 6 g de H 6,022 · 1023 átomos de O 1 mol de átomos de O 1 · 16 = 16 g de O
