Question

Ex.2: El Boro (B) tiene dos isótopos:
B-10 Masa: 9,99 u.m.a.
B-11 Masa: 11,03 u.m.a.
Si sabemos que la masa atómica relativa del Boro vale 10,81 uma, calcula la
abundancia relativa de los dos isótopos del Boro.

Ex. 3 El elemento magnesio (Mg) está formado por tres isótopos:
.- Mg-24 con abundancia del 78,70 % y masa isotópica de 23,98 uma
.- Mg-25 con abundancia del 10,13 % y masa isotópica de 25,02 uma
Si la masa atómica relativa del magnesio es de 24,31 uma, calculad la masa
isotópica relativa del Mg-26.
