Question

the two questions in the table are conceptual.

  1. what do you think is the closest average atomic mass for this element?

a. 15.5
b. 16.0
c. 16.5
d. 17

Explanation:

Step1: Calcular la contribución de cada isótopo

Para el primer isótopo: \(15.995\times0.9976 = 15.957612\)
Para el segundo isótopo: \(16.999\times0.0004=0.0067996\)
Para el tercer isótopo: \(12.999\times0.002 = 0.025998\)

Step2: Sumar las contribuciones

\(15.957612+0.0067996 + 0.025998=16.0\) (aproximadamente)

Answer:

B. 16.0
