Un compuesto ZO2 tiene masa molar igual a 64. La masa atómica de Z debe ser: A . 6. C. 12. E. 32. B. 10. D. 24.
9966 [12]

Answer:

32. Opcion E

Explanation:

ZO₂ podemos entenderlo como dióxido de Z

1 mol de ZO₂ contiene 1 mol de Z y 2 moles de O₂ por lo que si la masa molar es de 64 g/mol, podemos plantear lo siguiente

Masa de Z + 2 masa de O = 64 g/mol

Sabemos que la masa del oxígeno es 16 g/mol

x + 2. 16 g/mol = 64 g/mol

x = 64 - 32 →  32 g/mol

La masa atómica coincide con la masa molar, por lo tanto la masa atomica de Z es 32.
