Una muestra de 1 gramo de un elemento contiene 1,5 x 1022 atomos, cual es su masa molar❓❓
marusya05 [52]

El número de Avogadro es 6,022 x 10^23, y es el número de átomos que hay en un mol de dicho elemento. A su vez un mol es la cantidad de un elemento cuya masa en gramos coincide con el peso atómico.

Por tanto, 6,022 x 10^23 átomos del elemento tienen una masa en gramos igual a su peso atómico. Hacemos una regla de tres:


1 gramo -------- 1,5 x 10^22 átomos

x ------------------ 6,022 x 10^23 átomos


=> x = 40,1 gramos por mol del elemento.


De modo que su peso atómico es 40,1. Se trata del calcio.


Saludos.
