Answer:

107.86

Explanation:

La masa atómica de un elemento es la suma del producto de la masa isotópica relativa y la abundancia de cada isótopo.

Eso es:

masa atómica = suma (masa isotópica * abundancia)

Dado que un isótopo con una masa de 106.9 tiene una abundancia del 51.82% (0.5182) mientras que el otro isótopo con una masa de 108.9 tiene una abundancia del 48.18% (0.4818). Por lo tanto:

Masa atómica = (106.9 * 0.5182) + (108.9 * 0.4818) = 107.86
