Question

The relative abundance of three isotopes of silicon in nature is found to be as gollows. Si28=94.37% and Si30=2.46% . What is the average atomic mass of silicon?​

Answer 1

Answer:

28.08 a.m.u.

Explanation:

Average atomic mass =

$\frac{(28 \times 94.37) + (29 \times 3.17) + (30 \times 2.46)}{100} \\ = \frac{2642.36 + 91.93 + 73.8}{100} \\ = \frac{2808.09}{100} \\ = 28.08$
