Answer 2

Atomic mass is the sum of number of protons and of neutrons.

Silicon contains fourteen protons and fourteen neutrons in it.

So, it's atomic mass is 28 u.

i.e.

Atomic Mass of Silicon = Number of protons + Number of neutrons

=> 14 + 14 = 28 u

$\textbf{28 u is the Atomic Mass of Silicon}$
