beks73 [17]

Answer:

63.5474U.M.A. es la masa atómica promedio del cobre

Explanation:

La masa atómica promedio de un átomo es definida como la suma de las masas de los isótopos multiplicada por su abundancia. Para el caso del cobre que tiene dos isótopos:

Cu = Masa 65Cu*Abundancia + Masa 63Cu*Abundancia

Reemplazando con los valores dados en el problema:

Cu = 62.9298U.M.A.*0.6909 + 64.9278U.M.A.*0.3091

Cu = 63.5474U.M.A. es la masa atómica promedio del cobre
